V-band monolithic AlGaAs/InGaAs/GaAs PM-HFET mixers

MMIC microstrip single‐gate cold mixers and dual‐gate mixers have been developed, fabricated, and measured in V band. They have been processed on 0.15 or 0.25‐μm‐gate AlGaAs/InGaAs/GaAs pseudomorphic HFET technology. The devices are formed from an exhaustive methodology based on complex characterizations, specific nonlinear modeling and reverse engineering. A comparison for each MMIC is described from the chip process, from the same technology, under the same specifications. © 1997 John Wiley & Sons, Inc. Microwave Opt Technol Lett 15: 139–144, 1997.
