The VTS-5754F pulsed-coupled cavity TWT covers 3.1 GHz to 3.6 GHz with 160 kW peak output power,

up to 8% duty cycle. This device has a non-intercepting grid pulsed and single stage depressed collector to

achieve 48 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 200 micro

seconds in this PPM focused TWT
