Overview
The Murata Electronics SF1192B is a Surface Acoustic Wave (SAW) filter designed for RF signal conditioning in cellular communication systems. It operates at a center frequency of 1.843 GHz with a bandwidth of 75 MHz and insertion loss of 2.2 dB. The component utilizes a 6-SMD, no-lead package measuring 3.00 mm x 3.00 mm. It supports board mount installation and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Optimized for DCS band RF applications in mobile devices
- Compact surface-mount design for space-constrained PCB layouts
- High-frequency stability using SAW technology
Applications
- DCS band cellular phone RF front ends
- Mobile device signal conditioning modules
- Wireless communication baseband interfaces
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status directly with Murata Electronics or authorized distributors before procurement. Confirm that the 6-SMD package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for any end-of-life notices or alternative part recommendations from the manufacturer.
Selection Notes
Select this component when a compact SAW filter is required for the 1.843 GHz DCS band. Consider the 2.2 dB insertion loss and 75 MHz bandwidth against system link budget requirements. Evaluate the 6-SMD package size relative to available board real estate. Compare performance metrics against other Murata SAW filters if broader bandwidth or lower loss is needed.
Part Context
The SF1192B belongs to Murata's SF series of SAW filters, which are widely used in wireless communication equipment. This series emphasizes miniaturization and high performance for mobile handset applications. The component serves as a critical element for filtering out-of-band signals in the DCS frequency range.
Replacement Considerations
No public substitute part numbers are confirmed for the SF1192B. Consult Murata Electronics for potential obsolescence management or equivalent product recommendations.
