SMD SAW Filter

SAW Filters can be widely used in various wireless communication systems, televisions, video recorders and GPS receivers. The main function is to filter excess noise, which is easier to install and smaller than traditional LC filters.
At present, there are many products with antennas on the market, such as: GPS, base stations and other products will use high-frequency antennas, and the products are getting smaller and smaller, and the structure is becoming more and more complicated. Therefore, the package of SAW Filter is gradually shifting from DIP to small SMD components.
