APELC MG20-1C-100NF Marx Generator

The APELC MG20-1C-100NF was designed to be incorporated into the world’s first fully-integrated, compact and portable High Power Microwave source developed with Texas Tech University. This generator was initially used to directly source a virtual cathode vacuum diode, which produced 2 – 4 GHz microwave energy with 100’s of MW. The Marx generator, with a 20-kV charge voltage and 20 stages, produced a 200 kV pulse onto a matched 20 Ohm impedance, resulting in a peak power of approximately 2 GW. Applications include HPM and high-voltage insulation studies.
