Abstract :
77 GHz LNAs and TWAs operating from DC to 80 GHz were fabricated successfully [1],[2] using a highly reproducible MODFET technology with mushroom gates of 0.16 ¿m length. Technology development and optimization were carried out using DC and RF wafer mapping. A high yield high performance transistor process required for 70 to 80 GHz applications was therefore established.
