Abstract
Provided is a 3-way balun for a double balanced mixer. This research provides a 3-way balun available for a planar-type double balanced mixer and a planar-type double balanced mixer employing the same. The 3-way balun includes a first output unit for receiving and outputting an input signal of a predetermined frequency; and second and third output units connected to the first output unit and outputting signals whose phase is different by 180 from a phase of a signal of the first output unit and amplitude is a half of an amplitude of the signal outputted from the first output unit.
