摘要

NRL独特的板束电子枪，产生3.5-4-A, 0.3 × 4 mm的电子束，在~ 20kv，已经成功地用于Ka和W波段的多kw放大器。94 ghz窄带EIK采用3腔电路，峰值输出功率超过7.5 kW，饱和增益为~35 dB。该ka波段放大器采用双交错阶梯耦合腔电路，在34 GHz时实现峰值输出功率>10 kW, 3db带宽为5 GHz，饱和增益为~15 dB。两种放大器的性能与模型和仿真结果非常吻合。

Multi-kW sheet beam amplifiers at Ka and W bands

NRL's unique sheet-beam electron gun, which produces a 3.5-4-A, 0.3 × 4 mm electron beam at ~20 kV, has been successfully used to power multi-kW amplifiers at both Ka and W bands. The 94-GHz narrow-band EIK uses a 3-cavity circuit to produce a peak output power of over 7.5 kW, with saturated gain of ~35 dB. The Ka-band amplifier uses a double staggered ladder coupled-cavity circuit to achieve a peak output power >10 kW at 34 GHz, with a 3-dB bandwidth of 5 GHz and saturated gain of ~15 dB. The performance of both amplifiers is in very good agreement with models and simulations.
