Abstract
A mixer comprises a differential input circuit that is configured to receive an input signal. The mixer comprises a tank circuit including a tuning capacitor arranged in parallel with an inductor. A resonant frequency of the inductor and tuning capacitor is substantially centered around a predetermined frequency of the input signal. The mixer comprises a mixer circuit that communicates with the differential input circuit and that is configured to receive first and second current signals and a second input signal. The mixer circuit is configured as a Gilbert cell double-balanced switching mixer for generating a differential mixer output signal as a product of the first and second current signals and the second input signal.
