Patent ID: 8064867

Claim:
A method in an integrated circuit transceiver for communicating over a plurality of frequency bands, the method comprising: receiving a first input signal in a first frequency band at a first input transistor pair; receiving a first local oscillation (LO) signal having a first LO frequency at a first switching pair of a first input section; producing a first down converted signal at an output node based on the first input signal and the first LO signal; receiving a second input signal in a second frequency band at a second input transistor pair of a second input section; receiving a second LO signal having a second LO frequency at a second switching pair of the second input section wherein the first LO frequency is a multiple of the second LO frequency and wherein the second LO signal is based upon the first LO signal; producing a second down converted signal at the output node based on the second input signal and the second LO signal; and conducting at least one of the first and second down converted signals in a radio frequency front-end signal path and filtering, amplifying, and producing an ingoing digital signal to a processing block.
