Abstract :
This paper reports the design and measurement of a dual band monolithic AGC amplifier to be used in transmit/receive modules for Telemetry, Tracking and Control (TTC) of satellite systems. The amplifier is also included in a multifunction Monolithic Microwave Integrated Circuit, MMIC, containing frequency converters. The block diagram of this chip is shown. The goal of the work is to reduce the number, size, and consequently, the cost of the circuitry actually in use, whilst maintaining performance, through the use of mature GaAs PHEMT technology. Issues such as circuit topologies, dc power consumption, circuit area minimization and optimization are all important factors that are addressed during the design.
