Tuneable Low Frequency Microwave Source

High voltage RF sources designed to deliver frequencies from 10's of MHz to 1 GHz can be excessively large systems due to the geometric dependence on the radiating wavelength and the high voltage insulation requirements. Past efforts have targeted specific frequencies with specific temporal signatures and typically require large overhead in ancillary devices. Applied Physical Electronics, L.C. offers a method for delivering frequency agile, high voltage RF with variability in the temporal signature. With a frequency range from less than 100 MHz to more than 500 MHz, and with antenna voltages in excess 600 kV, the proposed design offers frequency agility and variable signal damping in a very compact package and with minimal ancillary device requirements.
