摘　　要：设计了一款W波段32路全波导带宽、高效率功率合成器。该器件采用E-H面T型结混合的实现方法,提高了功率合成器的紧凑性。为了扩展多路合成带宽,引入脊波导传输线,并采用多节阻抗匹配阶梯、渐变式过渡等形式。该结构具有结构紧凑、全波导带宽匹配、高效率的特点。为了验证该方法,加工并测试了32路功率合成器背靠背结构。在W波段范围内,该结构回波损耗优于15 dB,插入损耗低于1.05 dB,相对带宽为37.8%,合成效率大于78.4%。实测结果证明了该设计方法的有效性,对于多路功率合成场景具有很好的应用价值。A 32-way wideband and high-efficiency power combiner operating at the W-band is designed.The component employs a hybrid E-H plane T-junction to enhance the compactness of the power combiner.To extend the combining bandwidth,ridge waveguide transmission lines are introduced,along with multi-section impedance matching steps and gradual transitions.This structure features compactness,wideband matching,and high efficiency.To validate the proposed method,a 32-way back-to-back power combiner was fabricated and tested.Experimental results show that the structure achieves a return loss better than 15 dB,an insertion loss below 1.05 dB,a relative bandwidth of 37.8%,and a combining efficiency exceeding 78.4%across the W-band.These results confirm the effectiveness of the proposed design method,demonstrating significant application potential for multi-channel power combining scenarios.
