325-W Linearized S-Band Traveling-Wave Tube Amplifiers for Satellite Downlink
Stellant Systems has now completed six shipsets of space-flight qualified 300-W S-band traveling-wave tube amplifiers (TWTAs) operating at 2.3 GHz in a radiation-cooled package. These ship sets are powering the latest generation of satellites S-band broadcast services in the U.S. The latest two ship sets have increased the saturated RF output power from 300 W to 325 W. The TWTAs are linearized at the satellite integrator using Folsom S-band linearized, channel amplifiers (LCAMPs). This paper will detail the shipset performance.
