Patents by Inventor Kenneth Wilbert Finley

Kenneth Wilbert Finley has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Solid state RF power switching network
    Patent number: 6794951
    Abstract: An RF matching network includes a switching element that quickly switching between a first matching sub-network and a second matching sub-network, such that the impedance of neither sub-network is coupled to the other when selected by the switch. In one embodiment, the switching element includes a bipolar transistor, a TRIAC device and a PIN diode. The PIN diode conducts or attenuates the RF signal depending on its bias voltage. The bipolar transistor controls the bias voltage on the PIN diode. The TRIAC device protects the bipolar transistor damage that can be caused from high voltages generated at the PIN diode when the PIN diode is not conducting the RF signal.
