Patent ID: 8260244

Claim:
An apparatus comprising: a first stage including: a plurality of master radio frequency (RF) devices each to receive a common incoming RF signal and provide an RF current, each of the master RF devices comprising at least one transconductor; a plurality of master local oscillator (LO) devices each coupled to an output of one of the master RF devices, each of the master LO devices to receive the RF current and mix the RF current with a master clock signal to obtain a mixed signal; a plurality of rotating switch devices each coupled to one of the master LO devices to cyclically switch the corresponding mixed signal to each of a plurality of mixer loads; the plurality of mixer loads each coupled to the plurality of rotating switch devices, each of the plurality of mixer loads to perform gaining and filtering of the corresponding mixed signal; a second stage including: a plurality of gain stages each coupled to at least one of the plurality of mixer loads to weight the output of the corresponding mixer load and to provide an output to a summer.
