XHF-581M+

Overview

The XHF-581M+ is a reflectionless high-pass filter from Mini-Circuits' X-Series, operating within a passband of 580 to 3000 MHz. It features a center frequency of 1.79 GHz and a bandwidth of 2.42 GHz. The device exhibits an insertion loss of 2.1 dB and provides high stopband rejection up to 50 dB. Designed for robust performance, it supports an operating temperature up to 105°C and utilizes a 24-VFQFN exposed pad package.

Feature Summary

• Reflectionless topology that internally absorbs and terminates stopband signals rather than reflecting them
• High stopband rejection capability for effective suppression of strong spurious signals and intermodulation products
• Suitable for operation in close proximity to high-power components due to elevated thermal tolerance

Applications

• Frequency upconverter assemblies requiring signal filtering
• Systems needing suppression of strong spurious signals
• Circuit designs sensitive to reflected power interactions

Procurement Notes

Verify the specific datasheet revision and ordering suffixes when sourcing. Confirm package compatibility with your PCB footprint. Ensure thermal management aligns with the 105°C operating limit. Cross-reference pinouts with official Mini-Circuits documentation to prevent integration errors during assembly.

Selection Notes

Select this component when traditional reflective filters cause instability due to signal reflections. It is appropriate for applications requiring high isolation without external termination resistors. Consider the VFQFN package constraints and thermal dissipation requirements relative to the system's power handling capabilities.

Part Context

This component belongs to Mini-Circuits' X-Series of reflectionless filters, which includes two- and three-section models designed for ultra-high rejection. The technology utilizes an absorptive filter topology to manage stopband energy internally, distinguishing it from conventional reactive filter designs found in standard RF circuits.

Replacement Considerations
