A 1 kW electrostatically focused CW klystron for C-band communications

This paper discusses the development of a 1 kW electrostatically focused CW klystron amplifier for use in C-band microwave communication systems. It describes the electrical and mechanical design and performance characteristics of this tube. The utilization of the electrostatic focusing principle for a communication klystron amplifier results in some extremely attractive features for the designer of light-weight mobile microwave communication systems. The most important advantages are small size and low weight and the absence of any external focusing requirements, eliminating the need for heavy focusing magnets and eliminating stray magnetic fields.
