Thefrequencies of two input interdigital transducers are individually 180MHz and140MHz with the same bandwidth of 20MHz. The surface acoustic wave generatedby the input is coupled to the output which is composed with ten same structure IDTs.

• 它具有两个不同频率(140MHz、180MHz)、相同带宽(20MHz)的输入叉指换能器，通过耦合器将输入的两种不同频率信号单独或同时耦合于同一个由10个相同结构叉指换能器组成的延迟线输出结构中。
