Technical Note JAPAN CDMA/US CDMA SAW Duplexer "SD25 Series" SAW Duplexer "SD25 Series" Kyocera introduces CSP (Chip Size Package) type duplexer constructed by placing a SAW element, minimized with unique simulation technology, directly on ceramic substrate, and then sealed and coated with resin. Optimizing the combination of the SAW element and the substrate enables the duplexer to be as small as 2.5 x 2.0 x 0.8mm (typical value), making it the smallest duplexer in the industry. The product exhibits excellent resistance to climate and shocks because of its hermetic sealing with solder along the peripheral of the element mounted on the substrate.
