SF2223D

Overview

The SF2223D is a Surface Acoustic Wave (SAW) bandpass filter manufactured by RFMi, designed for signal conditioning applications. It operates at a center frequency of 184.32 MHz with a frequency range spanning from 169.32 MHz to 199.32 MHz. The device features a bandwidth of 30 kHz and supports a voltage rating of 30 V. Electrical characteristics include an impedance configuration of 50 Ohms and an insertion loss of 3.15 dB. It is housed in an 8-SMD surface-mount package, specifically the SM-13365-12 form factor. The component is qualified under AEC-Q200 standards and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides precise signal filtering with high selectivity at the 184.32 MHz center frequency
• Ensures efficient signal transmission through low insertion loss characteristics
• Complies with automotive reliability standards via AEC-Q200 qualification
• Utilizes a compact surface-mount design suitable for space-constrained PCB layouts

Applications

• Automotive electronic devices requiring robust signal conditioning
• Portable electronic systems needing stable frequency regulation
• Energy-efficient power supply circuits utilizing SAW filter technology

Procurement Notes

Verify that the specific order matches the 8-SMD package type and the 184.32 MHz center frequency specification. Confirm AEC-Q200 automotive qualification status if required for the target application environment. Ensure compatibility with the specified 50 Ohm impedance and 30 V voltage rating during system integration. Check for any specific handling requirements associated with Surface Acoustic Wave components.

Selection Notes

Select this component when a narrow bandwidth of 30 kHz is required around the 184.32 MHz frequency point. The 3.15 dB insertion loss makes it suitable for applications prioritizing signal integrity over minimal attenuation. The AEC-Q200 qualification indicates suitability for automotive environments, distinguishing it from general-purpose industrial filters. Consider the 8-SMD footprint constraints against available board space.

Part Context

This part belongs to the SF series of SAW filters produced by RFMi, formerly associated with Akoustis technologies. The series focuses on signal conditioning components optimized for specific frequency bands. The SF2223D represents a specialized variant tailored for the ~184 MHz range, differing from other series members like the SF2344D which targets 241 MHz operations.

Replacement Considerations

Direct substitutes must match the 184.32 MHz center frequency, 30 kHz bandwidth, and 8-SMD package dimensions. Verify that alternative parts maintain comparable insertion loss and AEC-Q200 certification levels for automotive equivalence.
