Abstract:
A mixer circuit includes a first oscillator, a second oscillator, an up-conversion mixer, a down-conversion mixer, and a detect and control unit. The up-conversion mixer has a first input terminal coupled to the first oscillator and an output terminal. The down-conversion mixer has a first input terminal coupled to the output terminal of the up-conversion mixer and a second input terminal coupled to the second oscillator. The detect and control unit is coupled to the down-conversion mixer.
