Tunable capacitor with RF-DC isolation |
摘要 |
A variable field effect capacitive device suitable for providing different amounts of capacitance in response to control signals of different magnitudes. The device includes a pair of plate electrodes and a pair of control electrodes. A semiconductor region is located between the control electrodes. The plates each make Schottky contact to the semiconductor region to form a depletion region therein which changes shape in response to changes in the magnitude of the control signals.
