WHITE PAPERS

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”.

The ICE4004 is an agile filter for both the VHF and UHF frequency bands. It allows simultaneous operation of a number of transceivers in the co-site environment. The VHF/UHF Filter provides significant RF selectivity to reduce broadband noise in transmit mode of operation and to reduce interfering signals at the transceiver’s RF input in receive mode. The design is highly integrated, including Built-in-Test, a failsafe bypass mode and an ARC-210 interface.
