Abstract
Integrated millimterwave heterodyne receivers for remote sensing applications in the frequency range 90 to 220 GHz utilizing active mHEMT devices have been designed, fabricated and characterized. Packages for the MMICs have also been designed and evaluated. For the integrated receivers, noise figures of 3.5 and 8dB are obtained at 100 and 220 GHz respectively at room temperature. When cooled to 20 K, a noise temperature of 60–80 K is obtained from 90–112 GHz for a packaged amplifier MMIC.
