Abstract
The principle and the optimum design method of 360° linear phase shifter are introduced, the physical definition of the principal technical specification is analysed and discussed. A 360° linear phase shifter with linearity of ±1.77% and bandwidth of 500 MHz using optimum designing method is designed, and a good effect in the application of synchronous phase shift scanning has been acquired.
