X-Band high power, low loss and fast switching twin-toroid type ferrite phase shifter is designed and fabricated. Differential phase shift (DPS), insertion loss, high power characteristics and impedance matching are determined and optimized using finite element solver in CST Microwave Studio. The effect of high order modes propagating in the structure is examined and methods to suppress these modes are investigated. <;0.8dB insertion loss and >15dB return loss is obtained for all phase states and operating temperature range in 12% bandwidth at X-Band. Switching time smaller than 10us is achieved using a digitally controlled high current driver circuit.
