Extended C Band 32 Watt SSPA for Communication Satellite Payload

Abstract

32W CW extended C band SSPA has been developed and qualified for communication payloads in geostationary satellites. The package is made structurally rigid and thermally stable to meet the qualification environment and temperature from −15°C to +65°C. The amplifier utilizes internally matched devices as output power amplifier stages in balanced configuration approach to allow good performance. The design is three tier configuration comprising of Driver amplifier package, High power amplifier package and EPC. Driver amplifier package design is based on low noise, high gain, wide band MMICs followed by medium power amplifier stages. High power amplifier package is realized with balanced configuration approach based on 90° hybrid coupler. 120W Electronic Power Conditioner (EPC) has also been developed and qualified for the SSPA.
