Abstract
A broadband transceiver includes an input to receive an RF signal, an output to output an RF transmit signal, a receiver section coupled to the input, and a transmitter section coupled to the output. A processor coupled to the receiver section and the transmitter section determines and generates an inverse waveform that will result in attenuation of undesired portions of a received RF signal when summed with the received signal, including optionally at one or more of an RF stage and an IF stage. A summing junction coupled between the processor and receiver section sums the inverse waveform with the received signal.
