SF2261E

Overview

The SF2261E is a surface acoustic wave (SAW) bandpass filter designed for RF signal conditioning applications. It operates with a center frequency of 880 MHz and provides a bandwidth of 60 MHz. The component features an insertion loss of 1.6 dB and is rated for a maximum voltage of 3 V. It maintains a standard impedance of 50 Ohms, ensuring compatibility with common RF transmission lines. The device is housed in a compact SM3030 package, specifically a 6-SMD, no-lead configuration, suitable for space-constrained printed circuit board layouts.

Feature Summary

• Utilizes surface acoustic wave technology for precise RF filtering
• Optimized for low insertion loss to preserve signal integrity
• Designed for general-purpose RF signal conditioning
• Compact surface-mount form factor for automated assembly

Applications

• RF front-end modules requiring 880 MHz bandpass filtering
• Wireless communication systems utilizing SAW filter stages
• Signal conditioning circuits in mobile or base station hardware

Procurement Notes

Verify the specific datasheet version from Akoustis or authorized distributors to confirm exact electrical tolerances and mechanical dimensions. Ensure the ordering suffix matches the required tape and reel packaging format. Cross-reference the part number against the manufacturer's current lifecycle status to confirm availability and compliance with RoHS standards before finalizing procurement orders.

Selection Notes

Select this component when a narrowband filter centered at 880 MHz with minimal signal attenuation is required. The 60 MHz bandwidth defines the passband characteristics, while the 1.6 dB insertion loss impacts overall system noise figure. Consider the SM3030 footprint constraints during PCB layout design to ensure proper thermal and mechanical performance within the target application environment.

Part Context

The SF2261E belongs to the RFMi product line, which is a brand under Akoustis Technologies. This series focuses on radio frequency components based on SAW, crystal, and ceramic technologies. These components are engineered for digital and wireless infrastructure, providing reliable signal processing solutions for modern telecommunications equipment and consumer electronics requiring high-frequency stability.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative SAW filters by matching center frequency, bandwidth, insertion loss, and package dimensions directly with the manufacturer's cross-reference tools or engineering specifications.
