3-WAY BALUN FOR A PLANAR TYPE DOUBLE BALANCED MIXER

摘要

PURPOSE: A three-way balun for a planar type double balanced mixer is provided to eliminate RF parasitic effect by excluding the section where two baluns overlap. CONSTITUTION: A first output unit(307) outputs an input signal with a received preset frequency. A second output unit(308) and a third output unit(309) are connected to the first output unit, forms 180 degrees with the phase of the first output unit, and outputs signals of half size.
