AB915B661-SFSM

Overview

The AB915B661-SFSM is a cavity bandpass RF filter manufactured by Anatech Electronics Inc. It operates within the 902-928 MHz frequency range, centered at 915 MHz with a bandwidth of 26 MHz. Key electrical specifications include a maximum insertion loss of 1.5 dB and a minimum return loss of 16 dB. The component provides rejection greater than 45 dB in the 850-894 MHz range. It features SMA connectors and is designed for outdoor applications.

Feature Summary

• Cavity construction for stable RF performance
• SMA connector interface options
• Outdoor environmental suitability

Applications

• Outdoor RF signal filtering
• 900 MHz band communication systems
• RF front-end modules requiring high rejection

Procurement Notes

Verify the specific connector configuration (SMA F/M) and mounting bracket requirements against the system design before ordering. Confirm that the 902-928 MHz operational range aligns with the target application frequency. Ensure mechanical dimensions and mounting methods are compatible with the intended enclosure or chassis layout to avoid integration issues during assembly.

Selection Notes

Select this component when a cavity filter topology is required for the 900 MHz ISM band. Consider the 1.5 dB insertion loss and 16 dB return loss limits as critical parameters for link budget calculations. Evaluate the physical size and mounting bracket needs for outdoor deployment scenarios where environmental sealing and structural stability are necessary for long-term reliability.

Part Context

Anatech Electronics Inc. specializes in RF filters, including cavity and LC types. The AB915B661 series represents their cavity bandpass offerings designed for robust performance in specific frequency bands. This model targets the 902-928 MHz range, distinguishing it from other models like the AE4000B6454 which operates at 4000 MHz. The company provides both standard and custom filter solutions for various RF applications.

Replacement Considerations

No public substitute part numbers are confirmed for this specific model. Direct replacement requires matching the 902-928 MHz frequency range, 26 MHz bandwidth, 1.5 dB max insertion loss, and SMA connector type. Verify mechanical compatibility if using alternative cavity filters.
