Abstract

This paper presents the design, simulation and measurement of two mode converting corrugated horns for application as the output launcher for a gyro-amplifier. Operating over the 90 to 100 GHz frequency range the horns act to convert the TE11 mode to the Gaussian-like HE11 mode. The difference in the horns is one was made initially to meet a more moderate Gaussian content specification while the other was improved to meet stricter criteria on Guassian content as-well-as being vacuum tight and compatible with integration with a broadband multi-layer vacuum window. The results are presented and show that in both cases the measured results agree well with simulated values and ultimately the second horn was demonstrated to be a good candidate to be tested on a gyrotron amplifier.
