    摘要: A semiconductor switching device includes two FETs with different device characteristics, a common input terminal, and two output terminals. The gate width of each FET is about 400 μm, and the maximum power required for the device operation is maintained by a lager conductivity of the channel layer of one FET and by a lower conductivity of the channel layer of another FET. The device operates at frequencies of 2.4 GHz or higher without use of shunt FET.

    摘要: A semiconductor switching device includes two FETs with different device characteristics, a common input terminal, and two output terminals. A signal transmitting FET has a gate width of 500 μm and a signal receiving FET has a gate width of 400 μm. A resistor connecting a gate electrode and a control terminal of the signal transmitting FET is tightly configured to provide expanding space for the FET. Despite the reduced size, the switching device can allow a maximum power of 22.5 dBm to pass through because of the asymmetrical device design. The switching device operates at frequencies of 2.4 GHz or higher without use of shunt FET.

    摘要: With a microwave FET, an incorporated Schottky junction capacitance or PN junction capacitance is small and such a junction is weak against static electricity. However, with a microwave device, the method of connecting a protecting diode cannot be used since this method increases the parasitic capacitance and causes degradation of the high-frequency characteristics. In order to solve the above problems, a protecting element, having a first n+-type region-insulating region-second n+-type region arrangement is connected in parallel between two terminals of a protected element having a PN junction, Schottky junction, or capacitor. Since discharge can be performed between the first and second n+ regions that are adjacent each other, electrostatic energy that would reach the operating region of an FET can be attenuated without increasing the parasitic capacitance.

    摘要: Since improvement measures are not taken in regard to the electrostatic breakdown voltage, electrostatic breakdown voltages, between the common input terminal IN—first control terminal Ctl-1, between the common input terminal IN—second control terminal Ctl-2, between the first control terminal Ctl-1—the first output terminal OUT1, and between the second control terminal Ctl-2—the second output terminal OUT2, where both ends of gate Schottky junctions of FETs are lead out to the exterior, are low. To solve the problem, the embodiment of the invention provides a switch circuit device, wherein protecting elements are connected by disposing two electrode pads, for connection to a single control terminal, on a chip and positioning the electrode pads near the common input terminal pad I and an output terminal pad O1 or O2. The electrostatic energies that are applied between the first output terminal OUT1—the first control terminal Ctl-1, between the common input terminal IN—the first control terminal Ctl-1, between the second output terminal OUT2—the second control terminal Ctl-2, and between the common input terminal IN—the second control terminal Ctl-2 can be respectively attenuated to the same degree and most efficiently.
