Abstract:
A differential mixer and a method which can reduce a leak component of a local oscillation differential signal are provided. A differential mixer includes a mixer core unit to which a high frequency signal and a local oscillation differential signal are inputted and which outputs an intermediate frequency differential signal, a common feedback unit which applies a bias voltage to a signal electrically coupled to the high frequency signal and to which a common voltage is fed back from the intermediate frequency differential signal, and a bias unit that applies a reference voltage to the common feedback unit. The common feedback unit generates the bias voltage based on the reference voltage. The bias unit controls the reference voltage so that a leak component of the local oscillation differential signal is a predetermined value or less at an output end of the intermediate frequency differential signal.
