Communication satellite power amplifiers: current and future SSPA and TWTA technologies
Aniceto, Raichelle; Cahoy, Kerri; Lohmeyer, Whitney (Wiley, 2016-04)This study captures the state of current satellite transponder technology, specifically, solid-state power amplifiers (SSPAs) and traveling wave tube amplifiers (TWTAs), and describes expected future advances, including ... -
Response of geostationary communications satellite solid-state power amplifiers to high-energy electron fluence
Lohmeyer, Whitney; Carlton, Ashley; Wong, Frankie; Bodeau, Michael; Kennedy, Andrew; e.a. (AGU Space Weather, 2015-05-25)The key components in communications satellite payloads are the high-power amplifiers that amplify the received signal so that it can be accurately transmitted to the intended end user. In this study, we examine 26 amplifier ... -
