A Calibrated Phase and Amplitude Control System for a 1.9 GHz Phased-Array Transmitter Element

Abstract

A system is proposed to allow the phase and amplitude of a signal to be accurately set and regulated over process and power supply variations. It uses a variable gain amplifier (VGA) in conjunction with the phase shifter to compensate for the variable losses of the phase shifter and simultaneously provide a means of adjusting the amplitude of the signal… (More)
