Abstract

A receiver circuit comprises a local oscillator (LO) signal generator that provides LO reference voltage signals, and a plurality of up-conversion paths that provide filtered up-converted signals. Each up-conversion path comprises a transistor and a bandpass filter. A drain of the transistor provides a mixed signal in response to one of the LO reference voltage signals at a gate of the transistor and an RF input signal at a source of the transistor. The bandpass filter has a fixed frequency that passes a first frequency component associated with a center frequency of the RF input signal and rejects a second frequency component associated with an undesired frequency in the mixed signal to provide one of the filtered up-converted signals. The fixed bandpass frequency may reject a plurality of second frequency components that are associated with a plurality of undesired frequencies of the RF input signal.
