Abstract

An efficient technique of phase noise reduction on TWT is introduced. The direct sampling of voltage ripple on each pulsed mode with voltage droop is achieved with a simple sub system which is independent of main microwave path. The compensation mechanism comprises of phase compensation with a microwave voltage controlled phase shifter to the input of TWT
