SF1224E-3

Overview

The RFMi SF1224E-3 is a Surface Acoustic Wave (SAW) filter designed for signal conditioning applications. It operates within a frequency range of 2.3194 GHz to 2.345 GHz, with a center frequency of approximately 2.3323 GHz. The component features a bandwidth of 25 MHz and an insertion loss of 0.6 dB. It is rated for a voltage of 3 V and maintains a 50 Ohm impedance. The device utilizes a 6-SMD, no lead package suitable for surface mount technology.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise RF filtering
• Provides low insertion loss for efficient signal transmission
• Designed for general-purpose RF applications requiring stable bandpass characteristics

Applications

• General purpose RF signal conditioning
• Wireless communication systems operating in the 2.3 GHz range
• RF front-end modules requiring bandpass filtering

Procurement Notes

Verify the specific datasheet version for the SF1224E-3 to confirm exact electrical tolerances and pin configurations before integration. Ensure compatibility with the target PCB layout for the 6-SMD package. Cross-reference the manufacturer's latest documentation to validate performance parameters against current design requirements.

Selection Notes

Select this component when a SAW filter with a 25 MHz bandwidth and 0.6 dB insertion loss is required at approximately 2.33 GHz. The 50 Ohm impedance matches standard RF systems. Consider the 6-SMD package size for space-constrained designs. Verify that the 3 V rating aligns with the system's power supply constraints.
