| Abstract: | A compact wide-band source based on Marx generator is designed, which is powered by a pair of 24 V,15AH（Ampere-Hour） lead acid batteries, inverted and multiplied to generate high-voltage alternating current（lOs of kV）. Marx generator is a compact ten-stage coaxial high voltage pulse generator with a total size of φ 150 mm ×550 mm. With a maximum of 20 kV charge voltage, this generator has an open circuit voltage of 200 kV. The fast voltage pulse generated by Marx source is applied directly to drive a spiral antenna. The experimental results show that the peak E field is 10.5 kV at a distance of 2 m from the radiation antenna, with a center frequency of 171 MHz. |
