SF2330K

Overview

The SF2330K is a general-purpose Surface Acoustic Wave (SAW) filter manufactured by RFMi. It operates at a center frequency of 1890 MHz with a bandwidth of 15.552 MHz, covering the range from 1881.79 to 1897.34 MHz. The device features an insertion loss of 2.2 dB and is designed for 50 Ohm impedance systems. It supports a voltage rating of 3 V and utilizes a 5-SMD, no-lead surface mount termination style.

Feature Summary

• Surface Acoustic Wave technology for signal conditioning
• General-purpose RF band pass filtering capability
• Designed for 50 Ohm system integration

Applications

• RF signal conditioning in wireless communication modules
• Frequency selection in mobile device transceivers
• Band pass filtering in general purpose RF circuits

Procurement Notes

Verify the specific package variant and tape & reel specifications against the official datasheet before ordering. Confirm that the 5-SMD no-lead footprint matches your PCB design requirements. Ensure compatibility with the 1890 MHz center frequency and 15.552 MHz bandwidth for your target application. Check for any specific handling or storage instructions provided by the manufacturer.

Selection Notes

Select this component when a SAW filter is required for the 1890 MHz band with moderate insertion loss characteristics. Consider the 5-SMD package size for space-constrained designs. Evaluate the 2.2 dB insertion loss against system link budget requirements. Ensure the operating voltage and impedance match the surrounding circuitry.

Part Context

This part belongs to the RFMi SAW filter family, which provides passive signal conditioning components for radio frequency applications. These filters are typically used to isolate specific frequency bands within complex RF front-end architectures. The SF2330K specifically targets applications requiring precise frequency selection around 1.89 GHz.
