High-Power Compact $P$ -Band UHF Oscillator Based on Hollow Cathode Discharge

This paper describes a novel high-power ultra high frequency oscillator based on hollow cathode gas discharge. The oscillator generates the pulses with a carrier frequency of 380 MHz, power of 390 kW, and pulse duration of 450 ns. The oscillator has been tested in a pulsed-periodical regime with a pulse repetition rate of 2.5 kHz. The lifetime of the oscillator is 10
⁷
pulses. The oscillator has been tested for operation into radiating three-element array of dipole antennas. These tests showed the oscillator and antenna array compliance.
