| 1. A method for processing signals in wireless receivers, the method comprising:
generating a control signal that enables a dual mode mixer within a RF receiver to operate in one of a plurality of modes,
wherein said control signal enables signal pass through operation or signal down conversion of a modulated input signal;
configuring said dual mode mixer to enable said signal pass through operation or said frequency down conversion based on said
generated control signal, wherein for said signal pass through operation said dual mode mixer outputs a signal that has a
same frequency as said modulated input signal; and
passing through or down converting said modulated input signal based on said configuration of said dual mode mixer.
