Gigatron, A New Technology For Microwave Power Devices Academic Article uri icon


  • The gigatron is a new design concept for microwave power devices. A gated field-emitter array is employed to produce microwave-modulated electron beam directly from the cathode. A ribbon beam configuration is used to mitigate space-change effects and provide efficient output coupling. A traveling wave output coupler is used to obtain optimum coupling to a wide beam. RF conversion efficiency is estimated at 75%. Gigatron-family devices have been designed for applications from 3 GHz to 60 GHz frequency, from 30 W microtubes for phased-array antenna drivers to 500 MW drivers for linac colliders. 1989 SPIE.
