Abstract:
A receiver includes a first local oscillator, and an in-phase mixer and a quadrature mixer coupled to the first local oscillator and configured to generate in-phase and quadrature signals based upon received RF signals. A complex mixer is downstream from the in-phase and quadrature mixers. A controller is coupled to the in-phase and quadrature mixers and is configured to determine when the in-phase and quadrature signals include interference less than an interference threshold, and then powers off one of the in-phase and quadrature mixers.
