Abstract
A phase shifter includes an FEThaving its drain electrode connected to an input/output terminal; and FEThaving its drain electrode connected to the source electrode of the FETand its source electrode connected to an input/output terminal; and FEThaving its drain electrode connected to the source electrode of the FET; and an inductorhaving its first terminal connected to the source electrode of the FETand its second terminal connected to a ground. It can reduce the insertion loss by narrowing the gate width of the FET, and carries out the phase shift of a high-frequency signal with suppressing the reflection.
