ABF-10R125G+

Overview

The ABF-10R125G+ is a thin film surface-mount bandpass filter manufactured by Mini-Circuits. It operates within a frequency range of 9.35 to 10.9 GHz, centered at 10.125 GHz with a bandwidth of 1.55 GHz. The component features a nominal insertion loss of 1 dB and provides high rejection up to 57 dB. It maintains a typical return loss of 11 dB and supports a 50Ω impedance environment. Designed for robust performance, it functions reliably across an operating temperature range of -55°C to 125°C.

Feature Summary

• Utilizes thin film technology for stable RF filtering in compact SMD packaging
• Provides high out-of-band rejection to suppress interference signals
• Optimized for low insertion loss to preserve signal integrity
• Engineered for wide industrial temperature operation stability

Applications

• Wireless communication systems requiring precise band selection
• RF test and measurement equipment signal conditioning
• Industrial measurement and control circuit filtering

Procurement Notes

Verify the exact part number suffix against official Mini-Circuits documentation to ensure correct specifications. Confirm package type and pinout compatibility with your PCB layout before ordering. Check current datasheets for any updates regarding operating temperatures or electrical tolerances. Ensure supply chain sources provide authentic components to avoid counterfeit risks.

Selection Notes

Select this component when a narrow bandpass response around 10.125 GHz is required. Consider its 50Ω impedance match for standard RF interfaces. Evaluate the thermal requirements against the -55°C to 125°C operational range. Compare insertion loss and rejection specs against system noise floor and interference levels.

Part Context

This device belongs to the Mini-Circuits ABF series of thin film bandpass filters. These components are designed for high-performance RF applications where size and stability are critical. The series offers various center frequencies and bandwidths to support diverse wireless standards and microwave systems.

Replacement Considerations

Consult Mini-Circuits official substitution guides for compatible alternatives. Verify that any substitute matches the 9.35–10.9 GHz frequency range and 50Ω impedance. Ensure physical footprint compatibility if replacing on existing PCBs.
