TWTA versus SSPA: a comparison of on-orbit reliability data

There has been long-standing debate regarding the comparative reliability of solid-state power amplifiers (SSPAs) versus traveling wave tube amplifiers (TWTAs) for the satellite downlink. High-voltage, thermionic, life-limited emitters operating in a high vacuum enclosure (i.e., a vacuum electronic...
