Description
A phase shifter is a key component to tune the phase of RF power for accelerating or deflecting structures in linear accelerators (linacs). This paper presents the design of a compact C-band variable phase shifter for our high-power test platform. It consists of a dual-polarization mode coupler and a movable short-circuited piston for adjusting RF phases. In order to isolate the coaxial port formed by the movable piston and the pipe a choke is introduced inside the piston. Through optimizations, the RF phase variation is simulated to be 10.1233°/mm of piston moving distance.
