Abstract:
1. 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 oscillator (LO) signal having a first LO frequency at a first switching pair; receiving a second input signal in a second frequency band at a second input transistor pair; receiving a second LO signal having a second LO frequency at a second switching pair; mixing the first input signal with the first LO signal to produce a first down-converted signal on a front end combined input path; mixing the second input signal with the second LO signal to produce a second down-converted signal on the front end combined input path; and filtering, amplifying, and producing at least one of the first and second down-converted signals on the front end combined input path to a baseband block.
