High efficiency, Ka-band, traveling wave tube amplifiers for intersatellite links
Abstract
Two high efficiency, 10-watt CW, Ka-band traveling wave tube amplifiers (TWTAs) are under development for Intersatellite Link communication applications. A goal of the effort is very high reliability and a 10-year life. The development includes both the traveling wave tube (TWT) and its electronic power conditioner (EPC). The application calls for the same tube design to operate at 22.55 to 23.55 GHz and 32.0 to 33.0 GHz. This wideband application requires that voltages be slightly different for the two bands; therefore, tubes will be channelized for either the lower or upper bands. The vacuum envelopes, however, are identical, as well as the packaging configuration. The high reliability space EPC is designed to accommodate both low band and high band TWTs.
