Abstract :
We report the design and gain performance for a two-stage 120-GHz monolithically integrated amplifier using 0.1-μm gate length pseudomorphic In/sub 0.60/Ga/sub 0.40/As/In/sub 0.52/Al/sub 0.48/As/InP HEMT´s. The two-stage amplifier demonstrated 10-12 dB gain measured between 119.5 to 123.5 GHz. To the best of our knowledge, this is the first demonstration of a monolithically integrated InP HEMT amplifier reported at D-band.
