Mitigating Self-Generated Communications Interference

Inadequate isolation between a transmitter and a receiver in a cosite environment results in the receiver’s diminished ability to process a weak desired signal- a condition termed “desensitization”.

This subsystem is an extremely high-Q agile transmit filter for the UHF frequency band. It enables clear channel operation of multiple transceivers in extreme cosite environments. The ICE4001 utilizes Trak-Pole® technology to provide excellent selectivity and broadband noise performance in a chassis that is a fraction of the volume and weight of a conventional filter approach. The ICE4001 is designed to mount directly to your system's cold plate or heat sink surface. It comes factory configured with a 16 bit serial interface. This filter/amplifier incorporates Built-in-Test capability and is qualified for helicopter applications. Minor modifications are available at a nominal cost. Please consult factory for details.
