SF1081A-1

Overview

The SF1081A-1 is a Surface Acoustic Wave (SAW) bandpass filter manufactured by RFMi. It operates at a center frequency of 71 MHz with a bandwidth of 280 kHz. The component features an insertion loss of 6 dB and supports surface mount technology in a compact package. Designed for signal conditioning, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides precise signal filtering at 71 MHz
• Compact surface-mount design for space-constrained boards
• Optimized for low insertion loss performance

Applications

• GSM intermediate frequency stages
• General-purpose signal conditioning circuits

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status before integration. Confirm that the 10-SMD package dimensions align with your PCB footprint requirements. Ensure the operating environment remains within the specified -40°C to +85°C thermal limits for reliable long-term operation.

Selection Notes

Select this component when a narrow 280 kHz bandwidth is required at 71 MHz. It serves as a suitable alternative to other SAW filters in GSM applications where moderate insertion loss is acceptable. Evaluate board space constraints against its small form factor.

Part Context

This part belongs to the RFMi SF series of SAW filters. These components are engineered for high-frequency signal processing tasks. The series typically offers various center frequencies and bandwidths tailored for communication systems requiring stable bandpass characteristics.

Replacement Considerations

Direct substitutes must match the 71 MHz center frequency and 280 kHz bandwidth. Verify pin compatibility for the 10-SMD package. Cross-reference insertion loss specifications to ensure signal integrity is maintained in the target circuit design.
