摘要

提出了功率放大器在相邻波束间共享的有源多波束馈电卫星天线结构。提出并比较了共享固态功率放大器(sspa)以降低k波段场景所需功率裕量的不同概念。在数据流量和雨水衰减分布不均匀的情况下，可以提高整体效率。

Architectures for efficient power sharing in active multiple-feed-per-beam satellite antennas

Architectures for active multiple-feed-per-beam satellite antennas with power amplifiers shared between adjacent beams are presented. Different concepts for sharing solid state power amplifiers (SSPAs) to reduce required power margins for a K-band scenario are proposed and compared. In scenarios with data traffic and rain attenuation unequally distributed across the beams the overall efficiency can be increased.
