发明名称 BROADBAND PHASE SHIFTER
摘要 PROBLEM TO BE SOLVED: To provide a phase shifter with a broadband characteristic without the need for increasing the circuit scale. SOLUTION: The broadband phase shifter is characterized in providing an adjustable phase and amplitude characteristics by utilizing a combination of a polyphase filter type four-phase power distributor for using a CR circuit to provide outputs of four signals whose phases differ from each other by 90 degrees each, and an x-degree phase shifter for providing outputs of four signals whose phase difference is an optional phase angle of 90 degrees or below.
