摘　　要：报道了采用 Zn O压电薄膜换能器设计制作倍频程宽带声体波微波延迟线和实际结果。工作频率 2～6 GHz,延时 0 .2 μs,插入损耗波动≤ 6 dAn octave band BAW microwave delay line based on ZnO piezoelectric thin film transducer is reported in this paper. Experimental results show the operating frequency of this delay line is 2～6 GHz with the time delay of 0.2 μs. The insertion loss ripple is less than 6 dB.
