Surface Acoustic Wave Components for RF Control Systems
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 10 to 300 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: ±100/±75/±50 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 +125 °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
■ 100% final examination
■ All EPCOS factories are certified to automotive standard ISO/TS 16949
■ Component qualification to automotive test procedure AEC-Q200
