Patents by Inventor Herbert P. Jacobson

Herbert P. Jacobson 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).

  • Power supply modulator circuit for transmitter
    Patent number: 5949296
    Abstract: The present invention relates to a power supply modulator for a radio transmitter having apportioned input impedance and buffered switching of power modules. A series arrangement of power supply modules, conventionally disposed in a diode cascade, includes individual inductors to apportion the input impedance of the switching power supplies. The switching sequence of the power supplies is controlled by a FIFO buffer, with the sequentially adjacent power supplies being disposed physically remote so that current transients and thermal loads are more uniformly distributed.
    Type: Grant
