The VTX-5786K family of pulsed-coupled cavity TWTs covers 8.4 GHz to 9.95 GHz the 5786K has 15 kW

peak output power, 6.0 % duty cycle. This device has a non-intercepting grid pulsed and dual stage depressed

collector to achieve 41 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, &

single stage depressed collector
