Pulsed high power microwave (HPM) oscillator with phasing capability

A pulsed, beamless HPM oscillator is described. The oscillator operates in the frequency band of 120-600 MHz and has a peak RF power of 1.8 GW. The oscillator produces bursts of HPM pulses having a length of 8-10 ns, containing 3 individual pulses, each having rise times on the order of 200 ps. The oscillator uses a custom-designed dipole antenna array to focus and radiate the device´s output RF energy. The referenced proprietary antenna array provides higher directivity in the operational frequency band and is specifically more efficient in the low-frequency portion of the radiated spectrum when compared to conventional Transverse Electric Mode (TEM) antennas having the same physical dimensions. The oscillator described above is a part of a phased multi HPM source system, capable of producing 12 GW of radiated RF power.
