ABSTRACT:
A single balanced mixer for use with a superheterodyne receiver or the like comprises an integrated structure characterized by a pair of opposed capacitive plates, a first mixing diode connected between the plates and a second mixing diode connected between one of the plates and a point of ground potential. A ferrite balun core is disposed between the capacitive plates and includes a first cavity receiving the first diode and a return conductor connected between two points of ground potential and a second cavity receiving the second diode and a return conductor connected between one of the plates and a point of ground potential. In another embodiment of the invention, a double balanced mixer comprises two interconnected integrated structures of the foregoing type, the diodes of one of the structures being connected having a polarity opposite that of the other.
