Getting a Grip On SAW Filters

Dec. 12, 2012
A free white paper provides basic information for specifying SAW filters.

Not only are compact filters, such as surface-acoustic-wave (SAW) filters, essential to the operation of many wireless communications devices, but many readers would be surprised how many of these passive components can be used in a wireless product. In some cases, a dozen or more filters and duplexers may be packed into a wireless electronic consumer products—especially one that provides multiple wireless services, such as a cellular phone, Bluetooth, and wireless-local-area-network (WLAN) capabilities.

Of course, SAW technology is one possible solution for delivering the necessary filtering functions to these products. But for those who would like a free education on SAW filters, Anatech Electronics is offering “Understanding SAW Filters and Duplexers” for download from their website.
