Abstract
A planar triply-balanced microstrip mixer for microwave and millimeter wave operation includes an RF port, and IF port and an LO port. The mixer is constructed on a single side of a two-sided substrate. The single side of the substrate supports an RF balun network connected to the RF port, an IF balun network connected to the IF port, and an LO balun network connected to the LO port; a pair of crossover diode ring quad circuits arranged in a planar back-to-back configuration; and a planar microstrip feed network connecting the RF, IF, and LO ports to the diode ring quad circuits through the RF, IF and LO balun networks.
