SF2215E

Overview

The RFMi SF2215E is a Surface Acoustic Wave (SAW) bandpass filter designed for signal conditioning applications. It operates at a center frequency of 1.96 GHz with a bandwidth of 65 MHz, covering a range from 1927.5 MHz to 1992.5 MHz. The component features a 50 Ohm impedance and a maximum insertion loss of 2.7 dB. It is housed in an SM-3030-6 surface-mount package with SMD/SMT termination. The device supports board mounting and functions within a temperature range of -45°C to +125°C.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise RF signal filtering
• Provides high selectivity with a defined 65 MHz bandwidth around the 1.96 GHz center frequency
• Engineered for low insertion loss to maintain signal integrity in passive circuits

Applications

• General purpose RF signal conditioning
• Wireless communication systems operating near 1.96 GHz
• Mobile device front-end modules requiring bandpass filtering

Procurement Notes

Verify the specific manufacturing source, as the SF2215E is associated with both RFMi and Akoustis. Confirm that the delivered components match the required SM-3030-6 package dimensions and RoHS compliance status. Ensure the supplier provides valid datasheets confirming the 2.7 dB insertion loss and 1.96 GHz center frequency specifications before finalizing orders.

Selection Notes

Select this component when a SAW filter is required for the 1.96 GHz ISM or cellular bands. The wide operating temperature range of -45°C to +125°C makes it suitable for industrial or automotive environments where standard commercial grade parts may fail. The 50 Ohm impedance ensures compatibility with standard RF transmission lines without additional matching networks.

Part Context

This part belongs to the SF series of signal conditioning filters manufactured by RFMi. These components are categorized under bandpass filters within the broader signal conditioning product line. The SF series typically targets general-purpose RF applications requiring compact surface-mount solutions for frequency selection and interference rejection.
