The Ferrite-Filter type of combiner has become the mainstay of operations in commercial and public safety systems.

EMR receiver multicouplers include a basic chassis on which a high performance, low noise amplifier and its power supply are mounted. A preselector is placed between the receiving antenna and the amplifier input according to the band of operation desired.

This bulletin addresses the ways in which RF Isolators are applied to control interference due to intermodulation products and to provide a variety of benefits.

The fifty ohms reference relates to the impedance of devices such as radio receiver input stages, transmitter power input and output stages, coaxial transmission lines and antenna systems.
