Abstract :
A low cost CMOS process controller for power amplifiers (PAs) in TDMA standards is presented. It fits into a 3×3 mm2 package for minimum PCB area. Low pin count imposes digital control by switching on the supply and monitoring steps of some millivolts. It prevents PA damage for high VSWR and uses ESD protection accepting negative voltages in an n-well process
