Jayaraj Microwaves manufacturers two type of power suppliers for the microwave beanches in X-Band.
Klystron power supply
For the Klystron based microwave bench. Klystron power supply generates required beam and repeller voltage for the X-band klystron tube like 2K25. It is very stable and contains the short circuit protection circuit. Also it has amplitude and frequency modulation circuits for the generations of 1 Khz squre wave and the saw tooth wave.
