Abstract

A compact and lightweight S-band 1 kW traveling-wave tube (TWT) is being developed for microwave power module (MPM) radar applications. The S-band MPM provides a tenfold peak power increase compared to the currently available ones. Circuit characteristics including interaction impedance, phase velocity, power, and gain of the TWT were predicted using large signal code. Design of electron gun, periodic permanent magnet, and collector is complete. The helix circuit has been fabricated and is ready to be tested.
