CPI MPP, Coupled Cavity TWT Operation - 3120 Hansen Way, Palo Alto, CA 94303-0750

The VTS-5753 pulsed-coupled cavity TWT covers 3.1 GHz to 3.5 GHz with 170 kW peak output power,

up to 16% duty cycle. This solenoid focused device has a non-intercepting grid pulsed and single stage

depressed collector to achieve 46 dB gain. This device is capable of parallel operation from a common HV

power supply, phase tracking is better than +/- 20 degrees. The long life CD coated cathode is capable of pulse

width to 1 millisecond.

The values listed above represent specified limits for the product and are subject to change. The data should be used

for basic information only. Formal, controlled specifications may be obtained from CPI for use in equipment design.
