The receiver mixes a local oscillator (LO) signal with the received signal to downconvert the received signal to an intermediate frequency (IF).

For low transmit power levels, the drive to the LO path is decreased, reducing power consumption in the communication device. In this way, receiver path noise due to mixing of the LO phase noise with the self-generated transmitter signal is selectively controlled while incurring lower power consumption penalty. The communication device may be an access terminal configured for communication with a cellular radio network.05-21-2009
