Abstract

Abstract

Coaxial inserting fin phase shifter is a new kind of high power microwave phase shifter. Based on the fundamental working principle of coaxial inserting fin phase shifter, numerical simulation and optimization design are presented and its structure and control system are discussed. A coaxial-inserting-fin phase shifter model with a central frequency of 4.1 GHz is designed and fabricated. Experiment has been carried out with the vector network analyzer, which shows that in the range of 4.0~4.2 GHz, the phase shifter can realize a phase shift of 90°, phase shift precision realizable can be 1° and phase shift precision is ±10°, the insertion loss of this phase shifter is over 1.5 dB．
