摘　　要：通过优化换能器拓扑结构、腔体结构和可调的微带匹配网络设计,研制出中心频率14 000 MHz、带宽1 500 MHz及延迟时间0.5μs的Ku波段声体微波延迟线。该产品的插入损耗为-56 dB,直通抑制大于45 dB,三次渡越抑制大于55 dB,产品综合性能指标优异。After optimizing transducer design, configuration and matching network, a microwave bulk acoustic wave delay line worked at Ku waveband with center frequency 14 000 MHz, bandwidth 1 500 MHz, delay 0.5μs was developed. The performance with insertion loss 56 dB, feed through suppression 45 dB and triple transmit- ting suppression（TTS） 55 dB, capability of product is excellllently.
