Abstract
0.1 cc high efficiency two-stage power amplifier multi-chip modules (PA MCM's) employing a novel resin multilayer printed circuit substrate and heterojunction FETs (HJFET's) has been successfully developed for 900 MHz band personal digital cellular phones. This power MCM with only 0.1 cc volume (7.0/spl times/7.0/spl times/2.0 mm/sup 3/) exhibited a power added efficiency of 60% with an adjacent channel leakage power of -49.25 dBc at an output of 30.0 dBm.Keywords
