ABSTRACT:
Methods and apparatus to provide an auxiliary receive path to support transmitter functions are disclosed. An example transceiver includes an antenna and a duplexer coupled to the antenna. A transmitter is coupled to the duplexer to output a transmit signal at a transmit frequency. A receiver is coupled to the duplexer to receive a received signal at a receiver frequency. A signal processor is coupled to the transmitter and receiver. An auxiliary receiver is communicatively coupled to the signal processor to receive the transmit signal output from the transmitter and send an auxiliary receiver signal to the signal processor. The signal processor adjusts the transmit signal based on the auxiliary receiver signal.
