High Power Squeeze Type Phase Shifter at W-Band.

摘要

We describe the design, fabrication and bench-study of a mm-wave phase-shifter employed as high recirculator for a traveling wave resonator circuit. The OFE cooper phase shifter was prepared by electro-discharge machining. Measured phase-shifter characteristics are presented and compared with theory. The phase-shifter was employed in a traveling wave circuit at 91.4 GHz with circulating power of 0.2 NW and subjected to fields greater than 10 MV/m without evidence of breakdown.
