Claim:
1. A receiver, comprising: filtering circuitry configured to perform low pass filtering and gain functions on a radio frequency signal provided by switch circuitry to generate a filtered radio frequency signal; a downconverter configured to generate a plurality of output phases based on the filtered radio frequency signal and a respective plurality of local oscillator signals, the plurality of output phases organized into at least K groups where K is an integer of four or greater, and each nth group of the K groups includes nth and (n+K)th output phases of the plurality of output phases, where n is an integer between 0−(K−1); and a differencing stage configured to difference the nth output phase of each respective group of the K groups with the (n+K)th output phase of the respective group, resulting in gain-added output phases.
