The Best Systems
Radiall’s engineers work with your engineers allowing us to develop the best competitively
priced misalignment RF coaxial interconnect solutions on the market today.
The Best Choices
Radiall offers more board 2 board choices with four different product groups and ten
connector series that can address the most demanding wireless telecom applications
required for the new generation of infrastructure compact equipment. From base stations
to repeaters and even handheld and GPS devices, we have a tailored connector solution
for you; including the new SMP-MAX, SMP-Spring, IMP-Spring and other large, limited and
no misalignment solutions.
SMP-MAX
Get the best for less with the new SMP-MAX large misalignment solution. Its patented impedance
matching insulator is optimized for a larger operating gap between connectors
making it easier for engineers to handle a board 2 board distance tolerance
of at least .078” (2.0 mm) without a spring, which is 300% more than the standard
SMP! It features a 3° minimum tilt (radiall travel) and it has an operating
frequency range of DC-6 GHz and a 1.2 max VSWR guaranteed at DC-3 GHz.
Spring-loaded Connectors
Radiall’s one connector IMP-Spring and three connector SMP-Spring and MMBX-
Spring large misalignment spring-loaded series are the best for increased maximum
distance tolerances.
IMP-Spring is a cost effective unique one connector solution that offers up to .023"
(.6 mm) board 2 board distance tolerance with a tilt (radial travel) up to 4.5°.
The new SMP-Spring and MMBX-Spring offer up to .078” (2 mm) board 2 board distance
tolerance and a 4.5° tilt (radial travel).
All spring-loaded solutions feature consistent VSWR and low RF leakage.
Limited Misalignment
Radiall’s one connector IMP and three connector SMP and MMBX limited misalignment series are
designed for applications requiring relatively precise distance tolerance of up to .023" (.6 mm) with
a tilt (radial travel) of up to 4.5°.
No Misalignment
Radiall’s MMT, MMS and MCX series are designed for applications requiring little or no distance tolerance between boards.

The cost-effective solution for maximum mechanical misalignment
Of the several RF connectors available for interconnections in wireless remote radio heads, repeaters, base stations,
GPS devices, and similar applications, the board to board style connector is growing in popularity. The product line
has evolved from accommodating limited misalignment to offering the widest tolerances available.
SMP-MAX is introduced by RADIALL to provide larger misalignment tolerances than the early version board to board
connectors like SMP or SMP-spring while offering lower cost.
Featuring an optimized interface, SMP-MAX can work up to 6 GHz board to board distance misalignment at least 2.0 mm
and radial misalignment 3° minimum.
The SMP-MAX series offers 2 levels of retention provided by the receptacles:
- Slide-on, for the lowest retention
- Snap-on, for a positive locking with a retention
A complete SMP-MAX board to board system is made of 3 parts:
Many other custom congurations are available. Larger distance misalignment and larger tilt versions are also
available.
