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

The VTS-5755 pulsed-coupled cavity TWT covers 2.7 GHz to 3.1 GHz with 60 kW peak output power,

up to 2.4% duty cycle. This device has a non-intercepting grid pulsed and single stage depressed collector to

achieve 50 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 50 micro

seconds in this PPM focused, air cooled TWT

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.
