A mode transducer was developed which generates high purity (>99%) TE/sub 02/ mode in small diameter (1.64 cm) circular waveguide. The device works from 52 to 62 GHz which allows relatively wideband, accurate swept frequency measurements of insertion and return loss in this mode. TE/sub 01/ to TE/sub 02/ insertion loss for the device is approximately 0.2 dB and the Te/sub 01/ mode rejection from the TE/sub 02/ port is 15 dB. A 2-degree linear taper is used to connect to 6.35 cm diameter waveguide. Mode purity of the TE/sub 02/ mode after this taper is >98%. Some typical measurements of waveguide components as well as a description of the device will be presented.
