Referenceless Canceler

The ICE2004 is an 8-channel RF Interference canceler system that achieves 40 dB of attenuation without the need for cumbersome reference signals from local transmitters. It is a simple two-port RF assembly that covers the 30 to 512 MHz frequency range.  The ICE2004 unit is placed directly between the receiver and its antenna. The ICE2004 enables the reception of low-level RF signals in the presence of up to 8 strong interferers as a result of its inherent low loss path for all non-canceled signals.

The ICE2004 provides fast canceler acquisition and is compatible with SINCGARS and Have Quick hopping waveforms. The canceler system is also designed for minimal harmonics and spurious signals and is MIL-STD-461F compliant. The power is MIL-STD-704F compatible. The unit will mount with standard military trays.


The ICE2004 can auto-tune to on or off board cosite emitters and also support ARC-210 and ARC-231 radio tuning. The canceler system supports IP addressable Ethernet for Built-In-Test (BIT) and system monitoring.

Cost-effective modifications are available on the ICE2004. 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.

Note: There are eight (8) large interfering signals in RED that are now attenuated by at least 40 dB in BLUE in this receive spectrum, which simultaneously reduces associated products in the receiver. The remaining desired signals are now readily discernible and receivable as a result of improved sensitivity in your collection/receiver system.
