  • RADIO FREQUENCY AND MICROWAVE SIGNALS
    Publication number: 20090206903
    Abstract: A device for generating high powered Radio Frequency (RF) or microwave signals comprising a fast rise-time video pulse generator, a modulator to modify the generated UWB pulses by gyromagnetic action to transfer a portion of the UWB pulse energy from lower frequencies to frequencies in the RF or microwave range thereby producing a resultant RF or microwave waveform that can be radiated.
