ABSTRACT:
A mixer device includes a differential circuit, a transconductance circuit, and a selecting circuit. The differential circuit receives a differential input signal and generates a differential output signal. The transconductance circuit is coupled to the differential circuit, receives a plurality of radio frequency input signals, and determines to mix at least one of the radio frequency input signals with the differential input signal according to an enable signal. The selecting circuit receives a control signal and generates the enable signal according to the control signal.
