3 Introduction What are SAW components used for? In remote control applications, SAW resonators provide stable frequencies for the RF carrier signal to transmit data over a range of 0 to 00 m or for the local oscillators of superhet receivers. The front-end filter in the receiver eliminates interference from the incoming RF signal, thus increasing selectivity and sensitivity in short-range devices. Benefits SAW resonators with tight frequency tolerances: ±00/±/±0 khz Identical pinning for all standard frequencies in each package size Hermetically sealed SMD packages allow the SAW components to operate even in extremely hostile environments: Extended operating temperature range from 40 C up to +2 C Improved shock and vibration strength thanks to stress-free cold seam-welding of the metal lid Enhanced reliability (particle protection) and reduced aging by patented PROTEC and ELPAS technologies 00% final examination All EPCOS factories are certified to automotive standard ISO/TS 6949 Component qualification to automotive test procedure AEC-Q200 Full level PPAP available Unique production know-how and volume benefits from the world market leader in SAW components: No less than three million SAW components leave our factories every day
