Abstract: In one embodiment, a method includes receiving and processing an incoming radio frequency (RF) signal in a receiver. Based on this signal, an environmental noise level can be determined, where this level corresponds to environmental noise present in an environment in which the receiver is located. Then, if the environmental noise level is substantially greater than receiver-generated noise, power consumption of at least one analog front end component of the receiver can be reduced.

Abstract: A system includes a cellular radio and an FM transmitter that are fabricated in the same semiconductor. The FM transmitter includes at least one mixer, a filter and an antenna tuning network. The mixer(s) translate an intermediate carrier frequency of an input signal to generate a second signal that has an FM carrier frequency. The filter removes spectral energy from the second signal to generate a third signal. The antenna tuning network is separate from the filter and produces a fourth signal to drive an antenna in response to the third signal.
