Abstract :
The design, fabrication, and experimental characteristics of a balanced InAlAs/InGaAs heterostructure diode mixer are presented. The mixer is monolithically integrated on InP substrates and shows a minimum conversion loss of 12.4 dB with a 91 GHz LO (local oscillator) drive of 12 dBm and an IF (intermediate frequency) of 2 GHz. A reasonably flat RF response has been found from 86.5 GHz to 95.5 GHz (10% bandwidth). The characteristics of the planar heterostructure diodes are studied, and the impact of their parameters on the mixer conversion loss is investigated. This diode design is the same as for high-electron-mobility transistors (HEMTs) and offers the possibility of easy monolithic integration with FET components as necessary for millimeter-wave modules.<>
