An intermediate frequency sidelobe canceller with provision for controlling the saturation level of the cancellation loop. Such control is provided by interposition of limiter means at a particular point in the cancellation loop, and it enables the setting or programming of the loop cancellation time constant as desired. It significantly enhances performance and reduces cost of the canceller loop by reducing substantially the signal power levels within the loop and by making the loop transient response essentially constant over a wide range of input power level.
