1.行波管用多级收集极提高行波管效率 Microwave J.(USA),Vol.18,№.8,pp.31～33,61,Aug.1975. 本文指出,通过回收行波管用过的电子注中的功率,可以提高其效率。作者叙述一种多级收集极技术,应使收集极效率达到85％,使总效率达到40％。设计用于14千兆赫新的卫星波段的行波管放大器 Microwaves(USA)Vol.14,№.6,pp.75～76 June.1975. 本文叙述1277 H 04R～028型行波管放大器,它用于满足14千兆赫新卫星波段的地面站需要。在20瓦输出功率下,其增益为53分贝。
1. Traveling Wave Tubes Use Multilevel Collectors to Improve Traveling Wave Tube Efficiency Microwave J. (USA), Vol.18, No. 8, pp. 31-33, 61, Aug. 1975. This paper indicates that the use of multi- The power of the electron injection can improve its efficiency. The authors describe a multi-stage collector technique that maximizes collector efficiency to 85% and total efficiency to 40%. Microwaves (USA) Vol. 14, No. 6, pp. 75-76, June 1975. A 1277 H 04R ~ 028 TWT amplifier is described in this paper Ground station needs to meet the new 14 GHz satellite band. At 20 watts output power, the gain is 53 dB.
