摘要

为了提高螺旋行波管的宽带性能，采用了正相速度锥化技术。利用该技术对小型行波管和中型行波管的慢波结构进行了优化。通过对均匀和正锥形螺距真空管的实际性能进行比较，发现后一种情况下，在工作频带的高端，效率和功率都有显著提高。

Improvements in Broadband Performance of Mini-TWTs at e2v technologies

Positive phase velocity tapering has been implemented to improve the broadband performance of helix traveling wave tubes (TWTs). The slow wave structures of a mini-TWT and a midi-TWT have been optimized using this technique. A comparison between the actual performances of the tubes with uniform and positive tapered pitch shows a significant improvement in efficiency and power at the higher end of the frequency band of operation in the later case.
