SF2202E

Overview

The RFMi SF2202E is a Surface Acoustic Wave (SAW) bandpass filter designed for signal conditioning applications. It operates within a frequency range of 2010 MHz to 2025 MHz, centered at 2017.5 MHz. The component features a 15 MHz bandwidth and maintains a 50 Ohms impedance. It has a rated voltage of 3 V and an insertion loss of 2.9 dB. The device is housed in an SM-3030-6 surface-mount package.

Feature Summary

• Surface Acoustic Wave technology for high-frequency signal filtering
• Compact SM-3030-6 surface-mount package design
• Optimized for general purpose RF applications

Applications

• General purpose RF signal conditioning
• Wireless communication systems operating in the 2 GHz range
• RF front-end modules requiring bandpass filtering

Procurement Notes

Verify the specific suffix variant required, as the SF2202E-1 exists with different insertion loss specifications. Confirm package compatibility with the SM-3030-6 footprint during PCB layout. Ensure supply chain sources provide official datasheets to validate electrical parameters against the target application requirements.

Selection Notes

Select this component when a narrow 15 MHz bandwidth is required around 2.0175 GHz. Compare insertion loss values between standard and -1 variants to match system sensitivity needs. Ensure the operating temperature range aligns with environmental conditions, as specific limits vary by variant.

Part Context

The SF2202E belongs to the RFMi SF series of SAW filters. This series includes various models such as SF2236E and SF2280E, covering different frequency bands from sub-GHz to multi-GHz ranges. These components are standardized for use in compact electronic devices requiring reliable RF signal integrity.

Replacement Considerations

The SF2202E-1 is a related variant with a specified insertion loss of 4.2 dB. Verify if the higher loss is acceptable for the circuit design before substitution.
