Abstract

A compact S-band 1 kW traveling-wave tube (TWT) is being developed for microwave power module (MPM) phased antenna array radar applications. The S-band MPM provides 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. The test result of the compact S-band 1 kW TWT will be presented along with design the results for individual components that include the electron gun, antennas, window, and collector.
