摘要 介绍了一种新型波导基空间功率合成器的结构设计.采用优化的Klopfenstein型鳍状天线阵,制作实现了C波段(3.2～4.9GHz)2×3层空间功率合成器.器件的外部结构尺寸为70.12mm×98.44mm×160mm,内部集成了6只内匹配的砷化镓微波单片功率管.对该器件进行了功率合成特性的测试,实测性能指标为:在4.2GHz,该器件在连续波输入下线性增益为8.5dB,饱和输出功率为42.82dBm(19.1W),功率附加效率为25.3%,功率合成效率达到72.3%. The configttration of a novel spatial power combiner in waveguide was introduced. Employing the optimized Klopfenstein tapered fin line arrays,the waveguide-based power combiner based on 2 × 3 arrays at C band was realized. Its size is 70.12mm × 98.44mm ×160mm and it was implemented by using six commercial GaAs MMIC amplifiers. CW power combiner measurements were performed,the linear gain is about 8.5dB,the saturation output power is 42.82dBm（ 19.1W）at 4.2GHz ,the PAE is 25.3 % and the efficiency is about 72.3 %.
