1.0 DEVICE OVERVIEW

The MRF24J40MA is a 2.4 GHz IEEE Std. 802.15.4™

compliant, surface mount module with integrated

crystal, internal voltage regulator, matching circuitry

and PCB antenna. The MRF24J40MA module oper-

ates in the non-licensed 2.4 GHz frequency band and

is FCC, IC and ETSI comp liant. The integrat ed modul e

design frees the integrator from extensive RF and

antenna design, and regulatory compliance testing,

allowing quicker time to market.

The MRF24J40MA module is compatible with

Microchip’s ZigBee®, MiWi™ and MiWi P2P software

stacks. Each software stack is available as a free

download, including source code, from the Microchip

web site http://www.microchip.com/wireless.

The MRF24J40MA module has received regulatory

approvals for modular devices in the United States

(FCC), Canada (IC) and Europe (ETSI). Modular

approval removes the need for expensive RF and

antenna design and allows the end user to place the

MRF24J40MA module inside a finished product and

not require reg ul atory testin g for an in tentional radiator

(RF transmitter). See Section 3.0 “Regulatory

Approval” for specific requirements to be followed by

the integrator.

2.0 CIRCUIT DESCRIPTION

The MRF24J40MA is a complete 2.4 GHz IEEE

Std. 802.15.4™ compliant surface mount module with

integrated crystal, internal voltage regulator, matching

circuitry and PCB antenna. The MRF24J40MA module

interfaces to many popular Microchip PIC micro-

controllers via a 4-wire serial SPI interface, interrupt,

wake, Reset, power and ground. Data communications

with the MRF24J40MA module are documented in the

“MRF24J40 IEEE 802.15.4™ 2.4 GHz RF Transceiver

Data Sheet” (DS39776). Refer to the MRF24J40 Data

Sheet for specific serial interface protocol and register

definitions.

2.1 Schematic

A schematic diagram of the module is shown in

Figure 2-1 and the Bill of Materials (BOM) is shown in

Table 2-1.

The MRF24J40MA module is based on the Microchip

Technology MRF24J40 IEEE 802.15.4™ 2.4 GHz RF

Transceiver IC. The serial I/O (SCK, SDI, SDO and

CS), RESET, WAKE and INT pins are brought out to

the mod ule pins. T he SDO si gnal is tri-st ate buf fered by

IC2 to solve a silicon errata, where the SDO signal

does not release to a high-impedance state, after the

CS pin returns to its inactive state. Crystal, X1, is a

20 MHz crystal with a frequency tolerance of

±10 ppm @ 25°C to meet the IEEE Std. 802.15.4

symbol rate tolerance of ±40 ppm . A balun is formed by

components: L1, L3, C2 and C14. L2 is an RF choke

and pull-up for the RFP and RFN pins on the

MRF24J40. C15 is a DC block capacitor. A low-pass

filter is formed by components: L4, C16 and C17. The

remaining capacitors provide RF and digital bypass.

2.3 PCB Antenna

The PCB antenna is fabricated on the top copper trace.

Figure 2-8 shows the trace dimensions. The layers

below the antenna have no cop per traces . The gr ound

and power planes under the components serve as a

counterpoise to the PCB antenna. Additional ground

plane on the host PCB will substantially enhance the

performance of the module. For best performance,

place the module on the host PCB following the

recommendations in Section 1.2 “Mounting Details”.

The Printed Circuit Board (PCB) antenna was designed

and simulated using Ansoft Designer® and HFSS™ 3D

full-wave solver software by Ansoft Corporation

(www.ansoft.com). The design goal was to create a

compact, low-cost antenna with the best radiation

pattern. Figure 2-9 shows the simulation drawing and

Figure 2-10 and Figure 2-11 show the 2D and 3D

radiation patterns, respectively. As shown by the

radiation patterns, the performance of the antenna is

dependant upon the orientation of the module.

Figure 2-12 shows the impedance simulation and

Figure 2-13 shows the actual impedance meas urement.

The discrete matching circuitry matches the impedance

of the antenna with the MRF24J40 transc eiver IC .

Host devices which contain separately certified

modules do not need to be recertified, provided that

they meet the fol low i ng con dit ion s:

a) The host device, as a stand-alone unit

without any separately certified modules,

complies with all applicable Radio S tandards

Specifications.

b) The host device and all the separately

certifie d modules it c ontains j ointly meet th e

RF exposure compliance requirements of

RSS-102, if applicable.

c) The host device complies with the

certification labeling requiremen t s of each of

the modules it cont ains .

From Section 5.2, RSS-Gen, Issue 2, June 2007,

Equipment La bels:

All Category I radio equipment intended for use in

Canada shall permanently display on each transmitter,

receiver or inseparable combination thereof, the

applicant’s name (i.e., manufacturer’s name, trade

name or brand name), model number and certification

number. This information shall be affixed in such a

manner as to not be removable ex cept by destruc tion or

defacement. The size of the lettering shall be legible

without the aid of m agnification, but is not required to be

larger than 8-point font size. If the device is too small to

meet this condition, the information can be included in

the user manual upon agreement with Ind ustry Canada.

Label:

From Section 7.1.6, RSS-Gen, Issue 2, June 2007,

Digital Circuits:

If the device contains digital circuitry that is not directly

associated with the radio transmitter, the device shall

also have to comply with ICES-003, Class A or B as

appropriate, except for ICES-003 labeling

requirem ents. The tes t data obta ined (for the ICES-003

tests) shall be kept by the manufacturer or importer

whose name appears on the equipment label, and

made available to Industry Canada on request, for as

long as the model is being marketed in Canada.

Note: Compliance of a module in its final

configuration is the responsibility of the

applicant. A host device will not be

considered certified if the instructions

regarding antenna configuration provided

in the original description, of one or more

separately certified modules it contains,

were not followed

To satisfy FCC RF Ex posu re requi rement s fo r mobile

and base station transmission devices, a separation

distance of 20 cm or more should be maintained

between the antenna of this device and persons

during op erat ion. To ensure co mplia nce, op eratio n at

closer than this distance is not recommended.

The antenna(s) used for this transmitter must not be

co-located or operating in conjunction with any other

antenna or transmitter.
