Abstract

A new on-chip linearizer self-adapting to the input power has been devised and implemented on a highly linear monolithic microwave integrated circuit (MMIC) power amplifier for 1.95 GHz wide-band code division multiple-access (W-CDMA) systems. The linearizer consists of an InGaP/GaAs heterojunction ...
