In this paper, a design method is proposed for the reflection type phase shifter applied to the DTV(Digital TV) receiver, and a phase shifter is designed by using the design equations to satisfy the phase shifting range over 180 degrees for frequency range from 470 MHz to 860 MHz, the receiving band of DTV. From the proposed method, it is possible that the systematic design of the reflection type phase shifter with desired phase shifting range and insertion loss. In addition, it is found that the realized phase shifter satisfies the given specifications.
