XBF-24+

Overview

The XBF-24+ is a four-section reflectionless bandpass filter manufactured by Mini-Circuits. It operates with a center frequency of 20 GHz and a bandwidth of 1 GHz, covering the range from 19.5 GHz to 20.5 GHz. The component features a nominal insertion loss of 6 dB and maintains a system impedance of 50 Ohms. It is constructed using a semiconductor IPD process and housed in a compact 24-lead VFQFN package with an exposed pad.

Feature Summary

• Employs a novel reflectionless topology that internally absorbs and terminates stopband signals rather than reflecting them.

Applications

• High-frequency RF signal processing systems requiring precise filtering at 20 GHz.

Procurement Notes

Verify the specific datasheet version for the XBF-24+ to confirm exact electrical tolerances and thermal characteristics. Ensure compatibility with 50 Ohm system impedance requirements. Confirm RoHS and REACH compliance status as indicated in official documentation before integration into final assemblies.

Selection Notes

Select this component when reflectionless performance is critical to prevent signal interference in sensitive RF chains. The integrated termination of out-of-band energy distinguishes it from standard reflective filters. Consider the 24-VFQFN package constraints for PCB layout and thermal management during the design phase.

Part Context

This part belongs to the Mini-Circuits XBF series of reflectionless filters. These components utilize internal absorption mechanisms to manage stopband energy, offering improved stability compared to traditional designs. The series is designed for applications where reflected power could degrade system performance or cause instability in active components.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify if other models within the ZXBF series offer compatible specifications if direct substitution is required.
