Abstract
A device comprises filter circuitry and non-linear mixing devices. The filter circuitry comprises a first port, a second port, a first bandpass filter, and a second bandpass filter. The non-linear mixing devices are responsive to control signals to couple poles of the first bandpass filter to respective poles of the second bandpass filter to cause non-reciprocal transmission of signals from the first port to the second port.
