Abstract

Abstract

This paper presents a compact wideband high power microwave source developed on the basis of a switched oscillator. To improve the operating voltage of the switched oscillator, it was filled with transformer oil for insulation. Furthermore, an electric-magnetic combined dipole antenna with relatively small physical dimensions and forward radiation pattern was employed as the radiating antenna. In the design stage, the performance of the switched oscillator and the radiating antenna was predicted by electromagnetic simulation. Then this wideband high power microwave source was tested in experiments and the radiated electric field was measured. As a result, the operating voltage of the switched oscillator exceeded 300 kV, while the radiation factor reached up to 125 kV and the central oscillating frequency was 375 MHz with a 3 dB bandwidth of 24%.
