PERFORMANCE SPECIFICATION

CONNECTORS, COAXIAL, RADIO FREQUENCY, GENERAL SPECIFICATION FOR

This specification is approved for use by all Departments

and Agencies of the Department of Defe nse.

1. SCOPE

1.1 Scope. This specification covers the general requirements an d tests for radio frequency

connectors used with flexible RF cable s and certain other types of coaxial transmissi on lines.

1.2 Classification. Connectors are of the following classes, categories, and Part or Identifying

Number (PIN), as specified (see 3.1).

1.2.1 Class. The class of connectors consists of the following:

a. Class 1 - A class 1 conne ctor is a connector which is intended to provide superior RF

performance at specified freque ncies, and for which all RF characteristics are completely

defined.

b. Class 2 - A class 2 connector is intended to provide mechanical conne ction within an RF circuit

providing specified RF performance.

1.2.2 Categories. The categori es of connectors are designated by an A (field serviceable), B (non-

field replaceable), C (field replacea ble solder center contact), D (field replaceable crimp center

contact), E (field replaceable) and F (field repla ceable crimp, for semirigid cable) as follows:

a. Category A - Connectors, which do not require special tools to assemble are de signated as

category A connectors. Standard wrenches, soldering equipment, pliers, etc., are not defined as

special tools.

b. Category B - Connectors, which require special tools to be assembled are designated a s

category B connectors. These con nectors may be used for original installations only. Field

replacement is intended to be made by categories A, C, D, E, or F con nectors, which will provide

the same form, fit and function. Category B connectors will not be stocked or procu red by the

Government.

c. Category C - Connectors, whi ch require only standard military crimping tools and standard cable

stripping dimension s to assemble, are designated as category C conne ctors. The standard

military crimping tool is as specified (see 3.1).

d. Category D - Connectors, whi ch re quire only standard military crimp tools for the center contact

and outer ferrule, and standard cabl e stripping dimensions to assemble are designated a s

category D connectors. The standard military crimp tool is as specified (see 3.1).

e. Category E - Connectors using semi-rigid cables with standard stripping dimensions and using

standard military tools. The method of assembly of the connector to the cabl e outer conductor

will be by solder.

f. Category F - Connectors using semirigid cables with standard stripping dimensions and using

standard military assembly tools. The method of assembly of the connector to th e cable will be

solderless.

1.2.3 PIN. The PIN consists of the letter “M” followed by the basic specificatio n sheet number, and a

sequentially assigned four-digit dash nu mber. The first digit in the dash number designates the material

and plating of the connector body (shell); i.e., “0” for silver plated brass, “3” for passivated corrosion-

resistant steel, “4” for gold plated copper beryllium, or "7" for nickel plated brass.

Example:

M39012/ 01 - XXXX

General specification Dash number from

specification sheet (see 3.1)

Specification sheet

The “-“ designates a standard military PIN. This position, when filled with the letter ‘B’ (i.e.

M39012/01BXXXX), signifies a military PIN, which is for OEM use only. The part is assembled to the

cable with special tooling. Acquisition of this type part by any agency other than OEM’s is prohibited and

will result in the substitution of the equivalent military replacement part (i.e., if “M39012/01BXXXX” is

submitted for acquisition, “M39012/01-XXXX” will be recommended.)

4.6 Methods of inspection.

4.6.1 Test methods. The following identified tests an d test methods assure connector integrity within

typical operating conditions and applications. Alternate commercial industry standard test methods

are allowed; however when an alternate method is us ed, the qualifying activity must be notified prior

to the performance of the test. The test method described herein are proven methods and shall be

the referee methods in case of dispute.

4.6.1.1 Visual and mechanical examination. Connectors a nd associated fittings shall be examined to

verify that the design, construction, physical dimensions, assembly instructions, marking and

workmanship are in accord ance with the applicable requirements (see 3.1, 3.3, 3.4, 3.28, 3.29, and

3.30).

4.6.1.2 Dimensional examination. Mating dimensions shall be exam ined by mating the connector

with its applicable mating gauges or oth er suitable means acceptable to the Government.

NOTE: The associated individual specif ication sheets show the overall dimen sion of the

connector when assembled to the appropriate cable. Mating interface dimension are to be

found in MIL-STD-348. The cable end construction a nd other dimensions are controlled by

performance requirements of the specification (i.e., cable retentio n, VSWR, RF leakage, etc.,

with cable in place).

4.6.2 Force to engage/disengage.

4.6.2.1 Bayonet and threaded types (see 3.5.1). The conn ector shall be engaged with its mating

standard part (see 3. 1). During the entire coupling/uncoupling cycle (until the connector is fully

engaged/disengaged) the forces and/or torques n ecessary shall not exceed those specified (see 3.1).

A threaded coupled connector i s fully engage d with its mating standard pa rt when their reference

planes (see MIL-STD-348) coincide. A bayonet coupled connector is fully engaged with its ma ting

standard part when the b ayonet studs have passed the detent an d their reference planes coi ncide.

No additional tightening torque shall be applied. The mating standard pa rt is a steel jig containing the

critical interface dimensions finished to the tolerances spe cified ( see MIL-STD-348). Its spring

members when applicabl e shall be heat treated beryllium copper. The surface finish or mating

surfaces shall be 16 microinches, maximum in accordance with ANSI B46.1.

4.6.2.2 “Push-on” connector types (see 3.5.2). The connector under test shall be engaged with its

standard mating part (gauge). Duri ng this engaging cycle the force neces sary to fully engage the

connectors shall not exceed that specified (see 3.1). Upon completion of engagement, an opposite

force necessary for disengagement shall be applied. This force shall be within the limits specified,

and shall include any unlatching forces required.

4.6.3 Coupling proof torque (see 3.6). The connector under test shall be eng aged with its mating

standard part (gaug e) and the coupling nut tightened to the torque value specified (see 3.1). After

one minute the connector under test and its mating standard part shall be disengaged.

4.6.4 Mating characteristics (see 3.7). After insertion of the specified oversi ze pin the specified

number of times (see 3.1), the contact to be tested shall be held rigid by means of a suitable jig or

fixture. A gauge containing the test pin or test ring and a suitable force indicating dial sh all be aligned

to within 0.004 TIR of any plane passing through the axis of the contact under test. Engagement or

withdrawal of the test pin or test ring shall be made smoothly and at such a rate that the dial do es not

bounce or otherwise give a false reading. The test pin or test ring may be chamfered to facilitat e

entry, but the specified engagement length shall not include the ch amfer length and the finish shall be

as specified and in accordance with ANSI B46.1.

MIL-PRF-39012E

4.6.5

Permeability of nonmagnetic materials (see 3.8). The permeability of the connector shall be

measured with an indicator conforming to ASTM A342.

4.6.6 Hermetic seal (see 3.9). Connectors shall be tested in ac cordance with method 112,

MIL-STD-202. The following details shall apply:

a. Test condition letter: C

b. Procedure number: I.

c. Leakage rate sensitivity: 10-8 cubic centimeters per secon d.

4.6.7 Leakage (pressurized) (see 3.1 0). Connectors shall be su bjected to air pressure specified (see

3.1) applied to one end, and the whole assembly immersed in water at a temperature of 15º to 25ºC.

The connector shall remai n immersed for at least 2 minutes.

4.6.8 Insulation re sist ance (see 3.11). Connectors without cables (wh en applicable) shall be tested

in accordance with method 302, test condition B, MIL-STD-202. Measure between the center contact

and body.

4.6.9 Center contact retention (see 3.12). An axial force (see 3.1) shall be applie d, first in one

direction and then the other, to the center conta ct of a n assembled and uncabled connector utilizing a

method and force measuring device suit able to the Government. The inner contact shall b e

inspected after the force has been applied in one dire ction and again after the force has been applied

in the opposite direction to determi ne if the contact has been displaced from the spe cified inte rface

dimensions. Torque: The torque specified shall be applied to the center co ntact of an unmated

connector for a minimum period of 10 seconds, as applica ble (see 3.1).

4.6.10 Corrosion (see 3.13). Unmated and uncabled connectors shall be tested in accord ance with

method 101, MIL-STD-202. The following details and exceptions shall apply:

a. Test condition letter: See 3.1.

b. Salt solution: 5 percent.

After exposure, connectors shall be washed, shaken and lightly brushed as specified in method 101

of MIL-STD-202 and then permitted to dry for 24 hours at 40ºC. Connectors shall then be examined

for evidence of corrosion, pitting, and ease of coupling.

4.6.11 VSWR (see 3.14). The VSWR shall be measured in accordance with the followin g procedure

or a method acceptable to the Government. In the event of dispute the method outlined herein shall

be used. Diagrams for the swept frequency VSWR system to check out the measurement

procedures are shown on figure 1.

In the basic measurement setup on figure 1, detector 1 provides a feedback signal to the swept RF

source in order to normalize the output signal of detector 2. The frequency-amplitude

characteristics of detectors 1 and 2 shou ld be matched within .5 dB.

MIL-PRF-39012E

To measure VSWR several sweeps are made with the slotted line probe incrementally positioned

over at least a half wave length at the lowest frequency of interest. In this manner an X-Y display is

generated whose upper and lower envelope limits represent maximum and minimum amplitudes of

the standing wave for each frequency in the test band. A base line may be generated by making a

sweep with no input to the measurement channel amplifier. The resultant X-Y display is calibrated

according to the characteristics of the measurement channel detector and amplifier, e.g., linear,

square law, logarithmic, etc .

The VSWR test system is checked out successively terminating the slotted line with the elements

shown in steps 1 and 2 and sweeping the frequency o ver the specified test band (see 3.1). In step 1

the system VSWR shall be less than 1.02 + .004 F (F measured in GHz). In step 2, the system

VSWR shall be as specified (see 3.1 ).

For qualification and group C inspection (see tables II and VII), the system is checked out with the

slotted line terminated as in step 3 using the spe cifie d cable (see 3.1). The impedance variation

(random and/or periodic) from the nominal characteristic impedance specified for the sele cted test

cable should be no mo re than 1.0 percent when tested by time domain reflectometry. In step 3, the

system VSWR shall be as specified (see 3.1). For qualification and group C inspection, the

connector under test is measu red with the slotted line terminate d as in step 4. The VSWR shall be

as specified (see 3.1).

Group B inspection tests (see table V) are performed with the slot ted line terminated as shown in

step 7. The input part of the cable simulator must have the same interface configuration,

dimensions, and dielectric as the recommended cable interface for the connector under test. The

cable simulator for group B inspection tests must meet the specified VSWR (see 3.1) when tested as

shown in step 6.

The standard preci sio n adapter interface shall conform to IEEE Standard 287. Item 6 (standard

precision adapters) shall not exceed the specified VSWR requi rements (see 3.1). Standard test

adapter designs shall be approved by the military qualifying agency.

4.6.12 Connector durability (see 3.15). Each connector under test shall be mated with a typical

production connector in accordance with this sp ecification. The conne ctor shall be subjected to the

number of cycles of mating and unm ating specified (see 3.1). The connector and its mating part shall

be completely engaged and completely disengaged during this cycle. Lubrication of the threads or

rotational parts shall not be employed for this test unless specified (see 3.1). It is permissible to

shake or blow debris from the threads or interface surfaces at intervals of not less than 50 cycles.

Solvents or tools shall not be used for cleaning.

FIGURE 5. Circuit diagram for RF high potential withstanding voltage.

4.6.21 Cable retention force (see 3.24). When specified (see 3.1), the connector shall be as sembled

to its standard mating test cable. The connector shall be firmly fixed and a movable sleeve attached

to the cable. The sleeve is then moved longitudinally away from the fixed connector gradually and in

such a manner that the cable remains unbent and untwisted. A scale for measuring the retention

force (see 3.1) shall be attached to the sleeve. The force shall be held for 30 seconds minimum. The

assembly shall then be examined for mechanical failure, loosening, or rupture and tested for

continuity using a suitable test method. When specified (see 3.1), a torque shall be applie d to the

cable about its axis in each direction relative to the connector at the location and to the torque value

given on the detail specification sh eet. The cable (flexible types only) shall then be bent at a radius of

MHz and 11 GHz, shall have a dynamic range from –20 dBm to better than –100 dBm or a difference

of 90 dB. Using +20 dBm RF source with 10 dB isolation, an additional 30 dB range can be obtained

by use of attenuator pads or a step attenuator producing a total range of 120 dB. The shortening

plunger is adjusted to produce a maximum reading in the detector with the triaxial assembly inserted.

The insertion loss caused by the insertion of the triaxial assembly a djuste d as shown is a measure of

the total leakage of the mated connector pair both at its interface as well as at the clamping points to

both cables.

Zorzy and RF Muehlberger, in the Microwave Journal, November 19 61, pp 80-86.

4.6.24 RF insertion loss (see 3.27). The connector shall be tested as shown on figure 8. Insertion

loss of a mated connector pair is defined as the increase of a loss due to insertion of a mated

connector pair in a cable; this includes the refle ction l osses to the cable and the dissipating losses in

the pair. First insert cable assembly number 1 and tune out its input VSWR by means of tuner

number 4 and balance setup. Then insert the cable assembly number 2 which includes the connector

pair under test. With tuner number 4 in the same po sition and the electrical length of the cable

assembly the same as that of number 1, record increase of insertion loss; add to this as a correction

the cable loss of the removed section due to the length ∆L1 + ∆L2 at this frequency. The sum of the

increase and the correction is the inse rtion loss of the connector pair. Use of alternate te st methods

may be approved by the qualifying activity.

ADDITIONAL INFORMATION ON TEST PROCEDURES

A.1 SCOPE

A.1.1 Scope. This appendix is a mandatory part of this specification. The information contained

herein is intended for compliance. This appendix is to provide additional information to the user of

this specification in performing the voltage standing wave ratio, RF leakage, and insertion loss tests.

A.2 TEST TYPES

A.2.1 Voltage standing wave ratio (see 4.6.11).

A.2.1.1 Test connector. The standard test-connector interface sha ll be in accordance with

MIL-STD-348. The standard test connector imp edance shall be 50 ± 0.5 ohms.

A.3 MEASUREMENTS

A.3.1 RF leakage (see 4.6.23).

A.3.1.1 Measurement technique. The measurement of the leakage from connectors is p erformed by

collecting the leakage energy in a coaxial system surrounding the l eakage source. An outline of the

instrumentation is shown on figure 7. The device from which leakage is to be measured is

incorporated on a uniform transmi ssion line which is terminate d in a matched load. The matched

termination simplifies both the measurement procedure and data reduction. This co mplete coaxial

system is embodied within a cylinder which forms, externally, a second coaxial system. The second

coaxial system is terminated at one en d in an adjustable short-circulating plunger and at the other in a

tapered transition terminated in a matche d detector.

For direct leakage measurements the a djustable short circuit serves several p urposes.

The short-circuit position i s adju sted to a ssure that an adequately low impedance appears behind the

equivalent leakage generator. A matched termination can be substituted, but the resulting 6-dB loss

cannot be tolerated in some cases. In addition, if the leakage source is directional, as it indeed is for

connectors with multiple leakage, it is possible for the leakage to be directed to this termination at

some frequencies and not collected by the dete ctor. For surface transfer-im pedance measurements

on connectors with leakage from more than one point in the connector, however, a matched

termination is desirable in order to simplify the transformation of the measured data to absolute

transfer impedance data. This is not ne eded to make relative com parisons in this test.

The equivalent leakage generator, in general, can have field components in the radial, axial, and

circumferential* directions. Furthermore, these components are n ot necessarily circularly symmetric.

Locally, TE, TM, and TEM modes can all exist, and in fact, for complete leakage measurement s, the

detector should couple to a ll but the measurement is more complex in this case. The excitation of the

outer coaxial line, however, is believed to be principally TEM, since the currents in the internal line are

predominantly axial and symmetric. It is however, possible to have a symmetri cal leakage current

which can generate the above mentioned modes. It is recommended that all measurements be made

below the frequency that the higher ord er modes can propagate in the outer coaxial line.

The characteristic impedance of the outer coaxial line of the tri-axial system, which is formed with the

inner conductor, should be matched to the detector. 50-ohm coaxial circuits a re generally desired for

convenience.

MIL-PRF-39012E

APPENDIX A

*NOTE: The circumferential E field compone nt is not usually present in axially symmetric

components.

The leakage power ratio is defined here as the ratio of the power detected to a 50 -ohm detector at the

output of the tri-axial unit to the power flowing through the internal 50-ohm conne ctor or cable system.

It is basically the attenuation through the tri-axial system. This definition appears arbitrary in the

sense that 50 ohms is an arbitrary load im pedance. However, since the leakage source impedance is

comparatively low, the voltage at the detector is essentially the open circuit leakage voltage. The ratio

of the input voltage to the leaky device to this output voltage is an absolute leakage quantity, as is the

measured power ratio, which is identical ly equal to the square of this voltage ratio.

The surface transfer impedance is obtained from this ratio as follows:

The surface transfer imped ance is.

11=e2

Where I1=Current flowing in internal line and

e2=Equivalent leakage voltage in external line.

In the connector leakage case, considering the equivalent leakage generator to be e2 with an

extremely low source impedance, this voltage e2 appears at detector terminals, and the adjustable

short circuit assures this. For a 50 -ohm transmission-line system, the input power is

501

The measured output power is:

22 (1)

The measured power ratio A2 is therefore,

e22

2 = 50 = e22 2

2 (50)2i

i 1

501 (2)

Substituting and by definition,

21 = e2 = 50 A (3)

The tri-axial system was set up principally to assess the relative le akage.

MIL-PRF-39012E

APPENDIX A

A.3.1.2 Measurement procedure. In measuring the leakage power ratio, A2, basically a substitution

technique is employed. A matched detector system is installed at the output connecto r of the tri-axial

unit, and the unit is driven as shown on figure 7. In this set-up, the short circuit is adjusted to produce

a maximum indication at the detector. The detector is then connected directly to the source and the

change of attenuation required to yield the initial detector level, is measured.

The sensitivity of this system is obviously limited by the sensitivity of the detector and the power

available. A sensitive parallel IF substitution system is employed, and for the low leakage

configuration about 100 milliwatts of power i s re quired.

The principal sources of error are attenuator errors and mismatch at the receiver (mixer) input. For

connector measurements, the error due to mismatch is directly proportional to VSWR sin ce the

equivalent leakage source impedance i s small. The indicated leakage power can vary between the

extremes. PxVSWR to P + VSWR, where P is the power that would be delivered to a matched

system. A VSWR of 2 will produce ± 3 –dB error therefore.

In advance of installing the inner coaxial system into the outer of the tri-axial system, the inner

system may be excited, and the immediate vicinity of the leakage point or associated connector and

attachment points probed with a small loop or dipole to establish how critical the mating, the

connector and joints are.

A.4 RF insertion loss (see 4.6.23).

A.4.1 The following procedure may be used wh en performing the insertion loss test of 4.6.24:

Assemble one 8” ± 1” long cable assembly terminate d in a male a nd female test connector. Record

its relative electrical length. Tune out its input VSWR using tuner numbe r 4. Do not disturb tuner.

For N, C, SC use M17/75-RG214 and “N” test connectors. For BNC, TNC, and TPS, use solid

copper shield cable equivalent of M17/111-RG303 (Co axitube number 1163.T1403-20 of Precision

Tube Co.) and TNC connectors. Measure insertion loss L1 of tuner number 4 and test cabl e.

Insert the connector pair to be tested in the middle, remove enough so that the electrical length is the

same as above within 0.05 cm, record ∆l1 + ∆l2 the total length of dielectric removed; keep tuner

number 4 in the same position as above. Measure insertion loss L2 of tuner number 4 and test cable

including connector pair.

Measure attenuation of 50 feet of test cable and compute loss

α per inch Lc = L2 – L1 + a (∆l1 = ∆l2).
