SF2434E

Overview

The RFMi SF2434E is a Surface Acoustic Wave (SAW) filter designed for signal conditioning applications. It operates at a center frequency of 1.223 GHz with a bandwidth of 54 MHz, covering a range from 1.196 GHz to 1.25 GHz. The component features a 50 Ohm impedance and a voltage rating of 3 V. It utilizes an SMD/SMT termination type in a 6-SMD, no lead package configuration. The device supports an operating temperature range from -45°C to +125°C.

Feature Summary

• Surface Acoustic Wave technology for precise RF filtering
• Optimized for GPS frequency bands
• Compact surface-mount packaging

Applications

• GPS receiver front-end modules
• GNSS positioning systems
• Mobile communication devices requiring L-band filtering

Procurement Notes

Verify the specific manufacturer designation, as RFMi products may be sourced through Akoustis. Confirm the exact package dimensions against the official datasheet before PCB layout finalization. Ensure supply chain documentation matches the required RoHS compliance standards. Check current availability status due to reported long delivery times and potential production delays.

Selection Notes

Select this component when a narrow bandpass filter is required specifically for the 1.223 GHz GPS L1 band. The 54 MHz bandwidth provides necessary selectivity while maintaining low insertion loss characteristics typical of SAW filters. Consider the wide operating temperature range for automotive or industrial environments where thermal stability is critical for consistent signal performance.

Part Context

This part belongs to the RFMi family of passive RF components, specifically within their SAW filter portfolio. These components are engineered for high-frequency signal integrity in compact electronic designs. The SF2434E serves as a specialized solution for filtering out-of-band noise in global navigation satellite system receivers.
