Abstract

An output system for a W-band (90-100 GHz) gyrotron-traveling wave amplifier is designed, simulated, measured and the results are presented. This is an updated system based on a previous design and the output shows more favorable properties for the amplifiers intended application, as a millimetre wave source in a cloud sensing radar. A greater than -30 dB reflection was measured over the frequency range and high Gaussian content obtained.
