SF14-1575M5UBB1

Overview

The SF14-1575M5UBB1 is a Surface Acoustic Wave (SAW) filter manufactured by KYOCERA AVX, designed for signal conditioning applications. It operates at a center frequency of 1575 MHz with a nominal impedance of 100 ohms. The device features an insertion loss of 1.7 dB and utilizes a 5-SMD, no-lead surface mount package. It is rated for operation between -30°C and +85°C. The component is moisture sensitive and supplied in reel packaging.

Feature Summary

• Surface acoustic wave technology for RF signal filtering
• Compact 5-terminal surface mount design
• Optimized for GPS L1 band signal processing

Applications

• GPS receiver front-end filtering
• GNSS navigation modules
• Satellite positioning systems

Procurement Notes

Verify the specific suffix 'BB1' against official datasheets to confirm pinout and electrical tolerances, as variations exist within the SF14 series. Confirm RoHS compliance status and Moisture Sensitivity Level (MSL) ratings prior to PCB assembly planning. Ensure storage conditions meet humidity requirements to prevent package degradation before reflow soldering.

Selection Notes

Select this component when a 100-ohm impedance interface is required for GPS applications, distinguishing it from standard 50-ohm variants. Evaluate the 1.7 dB insertion loss against system link budget constraints. Consider the -30°C lower temperature limit if operating in extreme cold environments compared to industrial-grade alternatives.

Part Context

This part belongs to the SF14 series of SAW filters from KYOCERA AVX. The series offers various center frequencies tailored for different RF bands. The SF14-1575 variant specifically targets the 1.575 GHz range, commonly associated with Global Positioning System signals. The product line emphasizes small form factors for portable electronic devices.

Replacement Considerations

SF14-1575F5UUA1 is listed as a discontinued alternative with similar 1.575 GHz specifications but differs in bandwidth and impedance characteristics.
