摘　　要：应用散射参数理论对大功率固态功放合成的效率进行计算推导,分析了合成效率的影响因素。基于概率论与数理统计的方法,对功率合成效率建立数学模型,提出了在不等幅、不等相位情况下,功率合成效率的理论数学期望。为功率合成效率预估提供了一种有效分析方法,同时也为大功率固态功放发射系统的研制提供了有力的理论依据。In this paper, we use the S-parameters to deduce the combine efficiency of high-power solid-state power amplifier and analyze the influence factors of combine efficiency. The mathematical model is established for the power combine efficiency basing on probability theory and mathematical statistics. The mathematical expectation of the power combine efficiency, under the condition of unequal power and out-phase is proposed. This research provides an effective analysis method for the power combine efficiency forecast and strong theoretical basis for the development of high-power solid-state power amplifier system.
