Abstract :
A W-band monolithic low noise AlGaAs/InGaAs/GaAs pseudomorphic HEMT amplifier mounted on a small hermetically-sealed package has been developed for use in Advanced Microwave Scanning Radiometer. A six-stage amplifier cascading three two-stage MMIC amplifier chips is assembled on a small hermetically-sealed package with waveguide interface and has achieved a noise figure of 4.3 dB with a gain of 28.1 dB at 91 GHz. The overall amplifier measures 12/spl times/32.8/spl times/5.4 mm/sup 3/. This is the first W-band multi-stage monolithic low noise amplifier mounted on a hermetically-sealed package.<>
