XHF-392+

Overview

The XHF-392+ is a reflectionless high-pass filter from Mini-Circuits, designed for signal conditioning in RF and microwave applications. It operates within a frequency range of 3.94 GHz to 11.5 GHz, providing a bandwidth of approximately 7.56 GHz with a center frequency around 7.72 GHz. The component features a 50 Ohm impedance and utilizes an SMD/SMT QFN-12 package with dimensions of 3.00mm x 3.00mm x 0.89mm. It exhibits an insertion loss of 1.3 dB to 1.6 dB and offers high stopband rejection up to 50 dB. The device functions reliably across a temperature range of -55°C to +105°C.

Feature Summary

• Employs a novel reflectionless topology that absorbs and terminates stop-band signals rather than reflecting them.

Applications

• Suppression of strong spurious signals
• Reduction of intermodulation products

Procurement Notes

Verify the specific datasheet version and electrical test conditions provided by Mini-Circuits before integration. Confirm that the QFN-12 package footprint matches your PCB layout requirements. Ensure thermal management strategies account for the specified operating temperature range of -55°C to +105°C during system design.

Selection Notes

Select this component when reflectionless performance is critical to prevent signal interference in sensitive RF chains. The wide bandwidth and high stopband rejection make it suitable for systems requiring effective suppression of unwanted frequencies without the standing wave issues associated with traditional reflective filters.

Part Context

This part belongs to the XHF series of reflectionless filters manufactured by Mini-Circuits. These components are engineered to provide superior signal integrity by terminating out-of-band energy internally. The series is designed for compact integration into modern RF systems where space and performance are paramount.

Replacement Considerations
