Abstract

A GaAs monolithic subharmonically pumped (SHP) Ka-band frequency converter has been developed. The complete frequency converter monolithic millimeter-wave integrated circuit (MMIC), having six microwave ports, consists of an SP2T RF switch, LO (local oscillator) buffer amplifier, anti-parallel diode mixer, three-stage IF (intermediate frequency) amplifier, and an SP3T IF switch. To minimize circuit cost, the converter was fabricated with conventional MMIC material and processing. The frequency converter exhibited a conversion gain of 8 dB and a single sideband noise figure of 20 dB. This IC is the first demonstrated monolithic Ka-band SHP frequency converter and has a higher level of integration than previous MMIC SHP mixers.<>
