摘要

介绍了高功率宽带三波束ka波段级联行波管(TWT)样机的研制进展。放大器将由一个电子枪(0.6 A × 3, 20 kV)驱动，该电子枪改编自我们的18束多束速调管设计。已经对级联行波管的蛇形和折叠波导两种版本进行了评估。在30ghz频率下，预期峰值射频输出功率为4.5 kW，驱动功率为100w。5ghz频段最小输出功率为3kw (> ~ 2ghz频段最小输出功率为4kw)。

Development of high-power broadband Ka-band cascaded-TWT

Progress on the demonstration of a high power broadband three-beam Ka-band cascaded traveling-wave tube (TWT) prototype is presented. The amplifier will be driven by an electron gun (0.6 A × 3, 20 kV) adapted from our 18-beam multiple-beam klystron gun design. Both serpentine and folded-waveguide versions of the cascaded-TWT have been evaluated. The expected peak RF output power is 4.5 kW with 100 W of drive power at a frequency of 30 GHz. The minimum output power is 3 kW over a 5 GHz frequency band (4 kW over > 2 GHz).
