SAW Filter For 3G（TD-SCDMA/WCDMA/CDMA2000） Repeater

Surface acoustic wave filter (SAW filter) is a small and thin filter using surface acoustic wave (SAW) excited on a piezoelectric substrate.  An SAW filter is an element used for removing noise and interference through selective pass of the bandwidth of a particular frequency (center frequency) by using piezoelectric characteristics that are inter-transducible between electricity and machinery.Surface acoustic wave (SAW) filters have a wide range of applications, including, for example, in mobile/wireless transceivers, radio frequency (RF) filters, intermediate frequency (IF) filters, resonator-filters, filters for mobile and wireless circuits, IF filters in a base transceiver station (BTS), RF front-end filters for mobile/wireless circuitry, multimode frequency-agile oscillators for spread-spectrum secure communications, code division multiple access/time division multiple access (CDMA/TDMA) access, clock recovery filters for fiber-optics communication repeater stages, synchronous, spread-spectrum communications, televisions, video recorders, and many other applications. SAW filters are also finding increasing use as picture-signal intermediate-frequency (PIF) filters, vestigial sideband (VSB) filters, and other types of communication filters, and as filters for digital signal processing.
