FABRICATION METHOD OF DOUBLE BALANCED MIXER

摘要

PURPOSE: A fabrication method of a double balanced mixer is provided to embed an inductor within a substrate in order to fabricate the inductor in small size and minimize interference between coils to enhance insulation characteristics and soldering characteristics of the mixer diode. CONSTITUTION: A fabrication method of a double balanced mixer comprises the steps of: forming a first trans by stacking plural dielectric sheets and conducting respective electrode pattern, and forming through hole electrodes for conducting the one end of the first trans and a mixer diode; forming a second trans by stacking plural dielectric sheets on a dielectric sheet having the first trans and conducting respective electrode pattern, and forming through hole electrodes for conducting the one end of the second trans and a mixer diode; printing a land pattern for mounting the mixer diode and then conducting the first and second trans; and forming an outer signal terminal for signal input/output.
