SF2001E

Overview

The RFMi SF2001E is a Surface Acoustic Wave (SAW) bandpass filter designed for signal conditioning applications. It operates with a nominal center frequency of 1960 MHz, covering a passband range from 1930 to 1990 MHz with a bandwidth of 60 MHz. The component features a 50 Ohm impedance and supports a maximum voltage rating of 3 V. It exhibits a typical insertion loss of 4.0 dB within the specified frequency range. The device is housed in a compact 6-pin SMD package, suitable for board mounting in wireless communication systems.

Feature Summary

• Surface Acoustic Wave technology for precise signal filtering
• Bandpass configuration centered at 1960 MHz
• Compact 6-pin surface mount design

Applications

• Wireless communication base stations
• Mobile handset RF front-ends
• Signal conditioning in cellular transceivers

Procurement Notes

Verify the specific package variant and tape & reel specifications against the manufacturer's current datasheet before ordering. Confirm RoHS compliance status and active production lifecycle status directly with RFMi or authorized distributors to ensure supply chain stability and regulatory adherence for your specific deployment requirements.

Selection Notes

Select this component when a narrow 60 MHz bandwidth is required around the 1960 MHz center frequency. Ensure the system impedance matches the 50 Ohm specification and that the operating voltage does not exceed the 3 V rating. Consider the 4.0 dB insertion loss impact on overall link budget during circuit design integration.

Part Context
