介绍了采用级联技术制作的１０２３位声表面波匹配滤波器的工作原理、设计方法和实验结果。匹配滤波器的中心频率为６５．２８ＭＨｚ，编码速率为４．０８Ｍｂｉｔ／ｓ（抽头间隔为０．２４５μｓ），持续时间为２５０．７３５μｓ，自相关峰值与最大旁瓣比为２６ｄＢ。测试结果表明，采用适宜的设计方法和工艺技术可获得预期的性能。
The working principle, design method and experimental results of 1023 SAW matched filter made by cascade technology are introduced. The matched filter has a center frequency of 65.28 MHz and an encoding rate of 4.08 Mbit / s (tap spacing of 0.245 μs) for a duration of 250.735 μs with a peak auto-correlation peak-to-peak ratio of 26 dB. The test results show that the expected performance can be obtained using suitable design methods and process technologies.
