SF2424D

Overview

The RFMi SF2424D is a Surface Acoustic Wave (SAW) bandpass filter designed for general-purpose RF applications. It operates at a center frequency of 505 MHz with a bandwidth ranging from 500 MHz to 510 MHz. The component features a 50 Ohm impedance and an insertion loss of 2.8 dB. It is rated for a voltage of 10 V and supports SMD/SMT board mounting in an SM-3838-8 package. The device functions within a temperature range of -40°C to +125°C.

Feature Summary

• Surface Acoustic Wave technology for signal conditioning
• General-purpose RF bandpass filtering capability
• AEC-Q200 qualified reliability rating

Applications

• General-purpose RF signal processing
• Wireless communication systems requiring 505 MHz filtering
• Board-mounted RF front-end modules

Procurement Notes

Verify the specific datasheet version for precise electrical tolerances and thermal soldering profiles, as manufacturing revisions may alter parameters. Confirm that the SM-3838-8 package dimensions align with your PCB footprint design. Ensure compliance with RoHS directives if required by your regional regulations. Cross-reference the AEC-Q200 qualification status against your quality assurance standards before finalizing procurement decisions.

Selection Notes

Select this component when a 505 MHz center frequency with a 10 MHz bandwidth is required for RF signal integrity. The 50 Ohm impedance matches standard transmission lines. Consider the 2.8 dB insertion loss for power budget calculations. The wide operating temperature range suits diverse environmental conditions. Verify that the surface mount package fits the available board space constraints.

Part Context

The SF2424D belongs to the SF series of SAW filters manufactured by RFMi. This series focuses on signal conditioning components for radio frequency applications. The device utilizes surface acoustic wave technology to achieve selective frequency filtering. It is distinct from other models in the lineup by its specific 505 MHz center frequency and associated bandwidth characteristics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative SAW filters with matching 505 MHz center frequencies and compatible SM-3838-8 packages. Ensure any replacement maintains the 50 Ohm impedance and similar insertion loss specifications to preserve circuit performance.
