Overview
The RF1385D is a Surface Acoustic Wave (SAW) filter manufactured by RFMi, designed for wireless radio frequency signal conditioning. It operates at a center frequency of 869.85 MHz with a bandwidth of 900 kHz, covering a range from 869.68 MHz to 870.02 MHz. The component features an insertion loss of 5 dB and utilizes an 8-SMD, no-lead package suitable for board mounting. It is qualified under the AEC-Q200 standard, ensuring reliability for automotive applications.
Feature Summary
- Surface Acoustic Wave technology for precise frequency selection
- Automotive-grade qualification compliant with AEC-Q200 standards
- Compact surface-mount design for efficient PCB integration
Applications
- Wireless communication systems requiring 869 MHz band filtering
- Automotive electronic modules utilizing AEC-Q200 components
- Radio frequency signal conditioning in transmitters
Procurement Notes
Verify the specific datasheet version to confirm exact electrical tolerances and packaging details. Ensure compatibility with the target assembly process for 8-SMD no-lead packages. Confirm that the 869.85 MHz center frequency aligns with regional regulatory requirements for the intended application band.
Selection Notes
Select this component when a narrow 900 kHz bandwidth is required at 869.85 MHz. The 5 dB insertion loss represents a moderate trade-off between selectivity and signal attenuation. Consider the AEC-Q200 qualification if the deployment environment demands automotive reliability standards over commercial grade alternatives.
Part Context
RFMi, now part of Akoustis Technologies, specializes in RF components based on SAW, crystal, and ceramic technologies. The RF1385D belongs to their SAW filter portfolio, which provides frequency control elements for digital and wireless applications. This series supports various industrial and consumer electronics markets.
Replacement Considerations
No direct public substitute part numbers are confirmed for the RF1385D. Engineers should evaluate other 869.85 MHz SAW filters from Akoustis or competitors only after verifying identical bandwidth, impedance, and package dimensions.
