Abstract
For use in a system having a received signal path therein, the signal path including a mixer that modifies a carrier frequency of an information signal propagating through the signal path, an apparatus for, and method of, reducing an overall power consumption of the system and a radio device employing the same. The apparatus includes: (1) a received signal strength indicator ("RSSI") circuit, in communication with the signal path, that provides an RSSI signal that is a function of a power of the information signal and (2) a power reduction circuit, coupled to the RSSI circuit, that reduces a current draw of the mixer when the RSSI signal exceeds an upper threshold level, the overall power consumption of the receiver thereby reduced.
