摘要

介绍了用于NASA空间对地通信的大功率高效空间行波管放大器(TWTAs)的最新进展。新型k波段放大器的射频功率和效率为40瓦和50%，新型ka波段放大器的射频功率和效率为200瓦和60%。一个重要的性能指标，定义为行波管的射频输出功率与质量(W/kg)之比，比上一代ka波段设备提高了十倍。

High power and efficiency space traveling-wave tube amplifiers with reduced size and mass for NASA missions

Recent advances in high power and efficiency space traveling-wave tube amplifiers (TWTAs) for NASA’s space-to-Earth communications are presented in this paper. The RF power and efficiency of a new K-Band amplifier is 40 Watts and 50% and that of a new Ka-Band amplifier is 200 Watts and 60%. An important figure-of-merit, which is defined as the ratio of the RF power output to the mass (W/kg) of a TWT has improved by a factor of ten over the previous generation Ka-Band devices.
