Overview
The SF14-1575F5UUA7 is a Surface Acoustic Wave (SAW) filter manufactured by KYOCERA AVX, designed for Global Navigation Satellite System (GNSS) applications. It operates at a center frequency of 1.57542 GHz with a bandwidth of 3 MHz. The component features low insertion loss of 0.8 dB and utilizes thin-film multilayer technology for high-frequency performance. It is housed in a compact 5-SMD, no-lead package measuring 1.40 mm x 1.10 mm x 0.70 mm.
Feature Summary
- Utilizes thin-film multilayer technology for superior high-frequency signal integrity
- Optimized for GNSS reception with precise 1.57542 GHz center frequency tuning
- Compact surface-mount footprint suitable for space-constrained mobile designs
Applications
- Global Positioning System (GPS) receiver front-ends
- Mobile device location services
- Automotive navigation systems
Procurement Notes
Verify the specific suffix UUA7 against official datasheets to confirm the 0.8 dB insertion loss variant, as other suffixes may differ. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for End-of-Life notices or Not Recommended for New Design (NRND) status from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a low-profile SAW filter is required for L1 band GNSS signals. Ensure the design accommodates the 5-SMD no-lead package dimensions. Compare insertion loss specifications against system link budget requirements to ensure the 0.8 dB value meets sensitivity targets.
Part Context
This part belongs to the SF14 series of SAW filters from KYOCERA AVX. The series is characterized by its use of advanced thin-film multilayer technology, offering improved performance over traditional bulk acoustic wave devices in compact form factors for RF signal conditioning.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing PCB footprints if considering alternative manufacturers.
