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.

Claim (Index 10):
The differential mixer according to  claim 1 ,\n wherein the mixer core unit has a first mixer core that is a single balanced mixer formed by a first type semiconductor element, and a second mixer core that is a single balanced mixer formed by a second type semiconductor element, wherein a plus side signal of the intermediate frequency differential signal of the first mixer core and a plus side signal of the intermediate frequency differential signal of the second mixer core are electrically coupled, and wherein a minus side signal of the intermediate frequency differential signal of the first mixer core and a minus side signal of the intermediate frequency differential signal of the second mixer core are electrically coupled.
