  • Metal-insulator-semiconductor device phase shifter
    Patent number: 3996536
    Abstract: A microwave signal phase shifter using a metal-insulator-semiconductor (MIS) device is provided. In one preferred embodiment, one end of the device is coupled to a port of a circulator and the opposite end is coupled to ground. When the diode is switched from a first reverse bias state to a second forward bias state, the network switches from a first reactance to a second reactance and the reflection coefficient phase angle shifts.
