摘要

本文对一种49元ka波段放大器阵列进行了实验和数值研究。本研究旨在确定放大器阵列中各种损耗的来源。无源仿真数据证实，有源器件看到的负载匹配良好，并且大部分功率耦合到LSE/sub 10/模式。这意味着如果没有由于有源器件和相位校正介质透镜引起的相位和振幅变化，则应该发生相干功率组合。

Numerical and experimental investigation of losses in a tray based spatial power amplifier

This paper presents experimental and numerical investigations on a 49-element Ka-band amplifier array. This study is aimed at determining the origin of various losses in the amplifier array. Passive simulation data confirms that the load seen by the active devices is well matched and that most of the power is coupled to the LSE/sub 10/ mode. This means that coherent power combining should take place if there is no phase and amplitude variation due to the active devices and phase correcting dielectric lenses.
