Title
High-gain cascode MMIC's in coplanar technology at W-band frequencies
Other Title
W-Band Kaskoden MMICs mit großer Verstärkung auf der Basis von Koplanar Technologie
Abstract
Compact high-gain W-band multistage amplifier MMIC's have been developed in coplanar technology using 0.15- mu m AlGaAs/InGaAs/GaAs PM-HEMT's. The conventional dual-gate HEMT has been modified to include an additional interstage network between the common-source and the common-gate HEMT. The effect of stabilizing circuit elements has been investigated. A gain of 10 dB per cascode stage is obtained at 94 GHz. Multistage amplifier MMIC's with up to 40-dB gain have been realized.
