The APELC MG20-22C-2000PF is a megavolt-class Marx generator specifically designed to drive low-impedance loads. With a 50 kV charge voltage and an 18 Ohm source impedance, this generator will deliver a 500 kV, 1.1kJ pulse into a matched load with a peak power of more than 12 GW. This generator uses a patent-pending low impedance, parallel-switched topology, which makes it well-suited for a wide variety of High Power Microwave applications.
