| 20100289597 | HIGH POWER UHF SINGLE-POLE MULTI-THROW SWITCH - A single pole multiple-throw switch for switching an RF signal to one of a plurality of outputs includes coupling the signal to a throw junction, said junction having connected thereto a plurality of switch legs, each leg includes a high voltage shunt diode spaced one quarter-wavelength from the throw junction; each diode mounted at its cathode end to a capacitor and adapted to receive a bias; wherein a controller applies a first DC bias to a selected one of the diodes to cause the selected diode to operate in reverse bias mode, such that the selected diode mounted on the corresponding capacitor provides a low insertion loss to pass the RF signal from the transmission line through the selected leg and to one of the outputs; and applies a second DC bias to the other diodes to cause the other diodes to operate in forward bias mode such that the other diodes mounted onto the corresponding capacitor provides a high insertion loss for blocking the RF signal to the remaining outputs. | 11-18-2010 |
