The VTU-5790A pulsed- coupled cavity TWT covers 16.0 GHz to 17.0 GHz with 30 kW peak output power,

1 % duty cycle. This device has a non-intercepting grid pulsed and single stage depressed collector to achieve

46 dB gain.

Custom configurations are also available. These variations in the performance and configuration include: cooling

method (affects average power level),mechanical configuration, electrical and RF connections, multiple stage

depressed collector.

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