ABSTRACT:
A double-balanced monolithic microwave integrated circuit mixer is fabricated on a GaHs substrate with a radio frequency microstrip balun formed thereon and a local oscillator microstrip balun formed thereon. A crossover diode ring is also formed upon the substrate. The radio frequency microstrip balun and the local oscillator microstrip balun provide enhanced electrical isolation between a radio frequency port and a local oscillator port, enhanced spurious response suppression, and enhanced local oscillator noise rejection in only 0.021".times.0.048" of circuit area.
