Overview
The SF2147D is an active Surface Acoustic Wave (SAW) filter manufactured by RFMi, designed for signal conditioning applications. It operates with a center frequency of 157 MHz and provides a bandwidth of 20 MHz across a range of 147 MHz to 167 MHz. The component features an insertion loss of 7.8 dB and is rated for 3 V voltage operation with a 50 Ohms impedance. It is packaged in a compact SM3838 surface-mount format and holds AEC-Q200 automotive reliability ratings.
Feature Summary
- Utilizes SAW technology for precise radio frequency signal filtering
- Complies with AEC-Q200 automotive qualification standards
- Designed for integration into wireless communication systems
Applications
- Base Stations
- Wireless Communication Systems
- OEM Wireless Devices
Procurement Notes
Verify the specific package variant and tape/reel specifications against the official datasheet before ordering. Confirm that the AEC-Q200 rating aligns with your system's environmental requirements. Ensure compatibility with the 50 Ohms system impedance and 3 V operating voltage limits defined in the electrical characteristics.
Selection Notes
Select this component when a 157 MHz center frequency with 20 MHz bandwidth is required for base station or wireless infrastructure applications. The AEC-Q200 rating makes it suitable for automotive or high-reliability environments. Consider the SM3838 footprint for space-constrained designs requiring low insertion loss performance.
