DESIGN AND TEMPERATURE COMPENSATION OF A KU-BAND CHANNEL AMPLIFIER WITH ALC FOR A SATELLITE TRANSPONDER

摘要

This article describes the design, development and test results of a Ku-band channel amplifier with an automatic level control (ALC) system for a satellite transponder. A systematic temperature characterization and optimization procedure depending upon the measured data of the channel amplifier is presented. This procedure takes into account the effect of parameter variations from one unit to another and eliminates the conventional trial and error method to determine the optimum component values of the temperature compensation circuits.
