Abstract:
A radio frequency (RF) transceiver includes an RF transmitter that generates an outbound RF signal at a carrier frequency that is based on a transmitter local oscillation. An RF front-end receives an inbound RF signal that includes a desired signal component that is based on the outbound RF signal and that includes an undesired signal component. The RF front-end includes a first RF combiner module that attenuates the undesired signal component to produce a desired RF signal. A down conversion module generates a down converted signal from the desired RF signal based on a receiver local oscillation. A receiver processing module generates inbound data from the down converted signal. A frequency control module controls a frequency of the transmitter local oscillation and a frequency of the receiver local oscillation, based on an interference rejection signal, to control the attenuation of the undesired signal component.
