摘要
发射机在功率合成的时候,由于各固态功率源模块间存在着增益和相位的差异,会导致功率合成效率的下降。针对这一问题,本文通过建立增益和相位的一致性对功率合成效率影响的模型,并结合MATLAB软件进行计算模拟,得到不同增益和相位分布下的最低合成效率分布,为发射机功率合成系统设计提供了具体的相位和增益指标,并为发射机的评估和验收提供了有力的理论依据。
Abstract
The efficiency of power synthesis will be reduced due to the difference of gain and phase consistency between solid-state power source modules. In this paper, a model of the impact of gain and phase consistency on the efficiency of power synthesis is established. Base on this model, the synthesis efficiency distribution under different gain and phase distributions is calculated with the MATLAB software. The simulation results provide the specific phase and gain index for the transmitter design and a strong theoretical basis for the evaluation and acceptance of the transmitter.
