Abstract

While SIS and Schottky barrier mixers have demonstrated decreasing receiver noise temperatures up to 500 GHz in the last few years, there is still a lack of very low noise receivers above that frequency. The 2DEG device, which the authors have developed, is based on the same material combination which is used in HFETs, i. e. a heterojunction between AlGaAs and GaAs. The layers which form the heterojunction are grown by OMCVD. Devices are etched as mesas, with standard ohmic contacts. Typical dimensions of the active region are a length of 5-10 microns, and width of 50-100 microns.
