| Abstract: | A grid control pulsed TWT with depressed collector and PPM focusing system is reported in this paper. It operates at X-band and delivers peak output power of 1 kW with saturation gain of 47 dB. The duty cycle is 3%. The electron beam transmission is 95% with RF output at saturated condition. The efficiency is not less than 30% (excluding the heater power). |
