Multichannel Interference Canceller (MIC)

Pole/Zero’s MULTICHANNEL INTERFERENCE CANCELLER (MIC) system is a five channel VHF/UHF Cosite Interference Mitigation System (CIMS) designed to be installed between receivers and antennas with reference signals derived from coupling from offending, cosite emitters. The equipment significantly reduces the undesired RF signals from each associated emitter in order to mitigate against interference to the associated receivers. This is accomplished by injection of accurately scaled anti-phase image of the reference (interfering) signal.

The unit contains five channels, each of which can be selected to cover 30-88 MHz, 116-174 MHz or 225-400 MHz.

The canceller detects frequency changes automatically and the revised interference is cancelled – even with frequency hopping signals. Click here to watch a short video demonstration of Pole/Zero’s cancellation technology. Please contact your sales representative at 513.870.9060 or for details.
