SF2204E

Overview

The SF2204E is a Surface Acoustic Wave (SAW) filter designed for general-purpose RF signal conditioning. It operates at a center frequency of 1900 MHz with a bandwidth spanning 1880 to 1920 MHz. The component features an insertion loss of 2.7 dB within the specified frequency range and supports a rated voltage of 3 V. Packaged in an SM30 surface-mount format, it provides 50 Ohms impedance matching for integration into wireless communication systems requiring precise frequency selection.

Feature Summary

• Utilizes Surface Acoustic Wave technology for efficient RF filtering
• Provides band-pass characteristics centered at 1900 MHz
• Designed for surface-mount assembly in compact electronic devices

Applications

• Wireless communication modules
• RF signal conditioning circuits
• General-purpose radio frequency applications

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as SF2204E-1 exist with different electrical specifications like insertion loss and voltage ratings. Confirm package dimensions and lead-free status against the latest manufacturer datasheet to ensure compatibility with existing PCB layouts and regulatory requirements.

Selection Notes

Select this component for applications requiring a 40 MHz bandwidth around 1.9 GHz. Compare insertion loss values between standard and variant models to match system sensitivity requirements. Ensure the operating voltage rating aligns with the circuit design constraints before finalizing the part number choice.

Part Context

This SAW filter belongs to the RFMi family of passive RF components. It serves as a frequency-selective element in transceivers, distinguishing desired signals from noise. The device complements other band-pass filters in the lineup, such as the SF2205E, by targeting specific cellular or wireless bands.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Variants like SF2204E-1 share the base model but differ in performance metrics; verify if these differences meet application needs before substitution.
