Overview
The SF2017E is a Surface Acoustic Wave (SAW) filter manufactured by RFMi, an Akoustis brand. It operates at a center frequency of 1.22 GHz with an 8 MHz bandwidth, covering the range from 1.216 GHz to 1.224 GHz. The component features a 200 Ohm impedance and a 3 V voltage rating. It is housed in an 8-SMD, no-lead package. Typical insertion loss is specified at 3.4 dB.
Feature Summary
- General purpose RF signal conditioning using SAW technology
- Designed for specific frequency band filtering applications
- Surface mount construction for automated assembly
Applications
- RF signal path filtering in wireless communication modules
- Frequency selection in general purpose radio frequency circuits
- Signal conditioning in devices operating within the 1.22 GHz band
Procurement Notes
Verify the manufacturer part number SF2017E against official RFMi or Akoustis documentation to confirm specifications. Ensure the 8-SMD package type matches the design requirements. Check for any specific ordering suffixes that may indicate variations in tape and reel packaging or lead finish, as these do not alter the electrical function but affect handling.
Selection Notes
Select this component when a SAW filter is required for the 1.22 GHz frequency range. Consider the 200 Ohm impedance match for circuit integration. Evaluate the 3.4 dB typical insertion loss against system link budget requirements. Confirm the surface mount footprint compatibility with the PCB layout before finalizing the design.
Part Context
RFMi, now part of Akoustis, specializes in RF components based on SAW, crystal, and ceramic technologies. The SF2017E belongs to their SAW filter portfolio, designed for digital and wireless applications. This series provides frequency control and signal conditioning solutions for modern electronic systems requiring precise RF filtering.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult RFMi technical support for direct replacements or cross-reference compatible SAW filters with identical 1.22 GHz center frequency and 8 MHz bandwidth specifications.
