SF2085A

Overview

The SF2085A is a Surface Acoustic Wave (SAW) bandpass filter manufactured by RFMi. It operates at a nominal center frequency of 96 MHz with a bandwidth of 36 MHz, covering a range from 81 MHz to 111 MHz. The device features a maximum insertion loss of 17 dB and supports a voltage rating of 30 V. Designed for surface mount technology, it utilizes the SMP53-S-10 package. The component functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Surface Acoustic Wave technology for signal conditioning
• Bandpass filtering capability in the 81 MHz to 111 MHz range
• Compact surface mount packaging design

Applications

• Intermediate Frequency (IF) processing
• WiMax communication systems
• General purpose RF applications

Procurement Notes

Verify the specific ordering suffix against official RFMi documentation to ensure correct configuration. Confirm that the required quantity aligns with the manufacturer's standard reel packaging specifications. Ensure compatibility with the specified SMP53-S-10 footprint during PCB layout. Validate RoHS compliance status through current datasheets before finalizing procurement decisions.

Selection Notes

Select this component when a 96 MHz center frequency with a 36 MHz bandwidth is required for IF stages. Consider the 17 dB insertion loss specification for system link budget calculations. The wide operating temperature range makes it suitable for industrial environments. Verify that the 30 V voltage rating meets the circuit requirements.

Part Context

The SF2085A belongs to the SF series of SAW filters produced by RFMi, an Akoustis brand. This series focuses on low insertion loss components for wireless communications. The device integrates acoustic wave technology to provide precise frequency selection for digital and mobile applications.
