11 MW Rebuilt Modulator for 5.5 MW S-band Klystron
This is a rebuilt 11 MW pulsed power supply (modulator), which is fit to drive an L3 L5822 or CPI VKS-8262 5.5 MW S-band (2856 MHz) klystron. The peak output power of this modulator exceeds 11 MW. The PLC RF control system and a 220 W RF driver system are also included in the modulator.
 
a 5.5 MW klystron tube, which is sit
on an oil tank.
 
220 W RF driver to supply an input
power to a 5.5 MW klystron.
