Referenced Cancellers

Designed to cancel RF interference, our Referenced Canceller solutions are applicable for multiple markets, including defense, EW, and radar.



MPG offers a Multi-Channel Interference Canceler (MIC), that utilizes a classical referenced approach to significantly reduce strong interfering RF signals emanating from co-located emitters. MIC devices are also called Referenced Cancellers, as they cancel in-band interferers on the same mobile platform, enabling proper receiver operation in communications or collection systems.


An MPG Referenced Canceller constitutes a 5-channel rack-mount VHF/UHF cosite interference mitigation system, offering the following benefits:

  • Cancels in-band interferers on the same mobile platform 
  • Detects frequency changes of the interferer automatically and cancels the revised interference even with frequency hopping signals
  • Provides 5 channels, each of which can be selected to cover 30-88 MHz, 116-174 MHz or 225-400 MHz

Solution Brochure Case Study

Problem Solved

MPG Referenced Canceller solutions reject the interferer’s amplitude at the receive location and are designed to solve the following challenges:

  • Undesired RF signals from associated remitters
  • Situations where receive signal offset is changing over time due to frequency hopping of the signal


MPG Solutions are qualified for airborne platforms and ground mobile or shipboard communication systems. Our flexible solutions support multiple radio models, including ARC-225, ARC-231, ARC-210 and ARC-210D radios, providing built in agility to simplify future integrations with new technology.

Referenced Cancellers



The Referenced MIC contains five channels, each of which can be selected to cover either VHF Low (30-88 MHz), VHF High (116-174 MHz), or UHF (225-400MHz). Further, the MIC detects frequency changes of the interferer automatically and the revised interference is canceled, even with frequency hopping signals. This is accomplished by injection of accurately scaled anti-phase images of the reference interfering
