Abstract

A new converter of mode TE10 to TE20 was developed for application in spatial power controller in a rectangular waveguide with slot profile (Finline).lt permits conversion of a TE10 mode to TE20 mode, eliminating the TE10 mode. One concept in Ku band (14-14.5 GHz) was successfully tested. The converter allows a TE20 mode to be obtained with suppression of the TE10 mode at less than 22 dB. This converter was employed for a 2 W power amplifier with an efficiency of 85%. A new measurement technique was developed for measuring the electric field profile in the interior of the rectangular waveguide.
