Abstract

A family of 700-W Ka-band Coupled-Cavity Traveling-Wave Tubes (CCTWTs) has been successfully developed, built, and tested at Communications and Power Industries (CPI). These CCTWTs are capable of up to 700-W Continuous Wave (CW) output power with 2.0 GHz of instantaneous bandwidth. They were built with the intended use for the commercial satellite and military communication market. We discuss the design and successful demonstration of the family of CCTWTs, including the VTA-6428S2B prototype which achieved over 700-W (783-W maximum output power) with an overall efficiency reaching as high as 52%.
