Diplexer Preamplifier FAM-258EL Passes CS116 Testing Requirements

Metropole Products, Inc. (MPI) is home to expert engineers who develop sophisticated communications components that empower communication around the world. At MPI, our determination to maintain the highest quality standards in our design, manufacturing and assembly represents who we are and what we stand for.

The MPI Model FAM-258EL, Antenna Diplexer/Preamplifier, recently underwent CS116 testing and successfully passed all of the requirements.

The FAM-258EL is a UHF SATCOM Diplexer and Preamplifier, which includes a separate Diplexer Receive Channel Output and Preamplifier Input to allow the inclusion of an external RF Limiter. The purpose of CS116 testing is to ensure the FAM-258EL’s ability to withstand conducted susceptibility of high level pulsed RF power. The specific testing included RF pulses exceeding 300 volts, within the receive channel passband.

The pulse test includes current injection on the power (J4), transmit (J2 over shield), and LNA out (J3 over shield) ports and voltage injection on the Antenna (J1) port (center to shield). While the former is similar to CS116/DO-160 CH 22 and other MIL-STD testing, the latter is a special threat test requirement.

For more than 40 years, our expert engineers have helped both government and industry to reach farther, connect more clearly and share information more efficiently. We offer a broad spectrum of specialized products along with the proven expertise to design and manufacture customized solutions to meet the most demanding mission requirements.
