Reported the structure, design and performance parameters of a 31-bit SAW programmable matched filter. SAW programmable tapped delay line is widely used in recent years, a rapid development of DS technology. Its powerful signal processing capabilities and high computing speed, making the DSSS signal fast synchronization and matched filtering is greatly simplified than the traditional technology. The article reports the 31-bit surface acoustic wave low-frequency programmable tapped delay line is a key signal processing device used for spread spectrum anti-interference communication system. In the development process, new technologies such as COMS / SOS and new designs such as splitting taps are used to make the clock speed and the main sidelobe of the device significantly higher than the key technical indicators to fully meet the system requirements
