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

The VTX-5686C pulsed-coupled cavity TWT covers 9.5 GHz to 10.5 GHz with 120 kW peak output power,

30 % duty cycle. This device has a Mode-Anode pulsed and single stage depressed collector to achieve 48 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.
