Technology Summary
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.
