An 83-GHz two-stage cascode power amplifier (PA) implemented in a low-cost 200/180-GHz fT / f max 0.18-μm SiGe BiCMOS technology is presented. The power-combining technique based upon a low-loss two-way transmission-line current combiner has been employed that simultaneously addresses the gain requi...
