1. Low insertion loss surface acoustic wave filter
2. Low amplitude ripple
3. There is a sharp rejection at both exit points
4. Multiple packaging sizes, SMT and plugin packaging, such as TO39, QCC8C, QCC12, QCC12C, etc
5. Applied to various communication products, such as walkie talkies, wireless communication, base stations, receivers, communication terminals, and other product industries
