Abstract
We have fabricated 35-GHz balanced low-noise amplifiers using pseudomo rphic InGaAs-GaAs HEMT material monolithically integrated with HBT mat erial grown by selective MBE. The 0.2-mum T-gate HEMT amplifiers fabri cated using a merged HEMT-HBT process have equivalent gain and noise f igure compared to amplifiers fabricated using normal MBE and our basel ine HEMT-only process. This demonstration of high performance HEMT amp lifiers using integrated HEMT-HBT material and a merged HEMT-HBT proce ss enables the fabrication of a new class of multifunction monolithic microwave integrated circuits.
