Title: Microwave switching circuit
Inventor: WATANABE SHIGERU
IPC: H03K17/687
Filed: 1987-03-31
Abstract: PURPOSE:To reduce the insertion loss and to improve the isolation by connecting a diode between a gate of a field effect transistor (FET) and ground. CONSTITUTION:In bringing a gate bias voltage of a FET 1 to 0(V) by providing a diode Do between a gate G of the FET 1 and ground GND, the FET 1 is energized and the diode Do is turned off. Since the impedance between the gate G and the ground GND is large, the insertion loss is reduced. In applying a negative voltage over the pinch-off voltage to the gate G of the FET 1 at the off-state, the FET 1 is cut off and the diode Do is energized. Since the impedance between the gate G of the FET 1 and ground is small, the isolation is improved.
