XHF-482M+

Overview

The XHF-482M+ is a reflectionless high-pass filter manufactured by Mini-Circuits, designed for surface-mount technology (SMT) applications. It operates within a frequency range of 4800 MHz to 19400 MHz and maintains a system impedance of 50 Ohms. The component utilizes a patented two-section topology that internally absorbs and terminates stop-band signals, preventing signal reflections. This design ensures stable performance in RF systems without the need for external termination resistors.

Feature Summary

• Employs a patented two-section reflectionless topology to absorb stop-band energy
• Internally terminates reflected signals to prevent system instability
• Designed for surface-mount integration in compact RF circuits

Applications

• RF front-end modules requiring high-pass filtering
• Microwave communication systems operating above 4.8 GHz
• Test and measurement equipment signal conditioning

Procurement Notes

Verify the specific datasheet revision when ordering, as Mini-Circuits may update mechanical drawings or electrical specifications over time. Confirm the package type matches your PCB footprint requirements. Ensure the voltage and power handling ratings align with your system's operational limits before finalizing procurement.

Selection Notes

Select this component when reflectionless behavior is critical to maintain system stability in high-frequency designs. The internal absorption feature eliminates the need for additional terminations, simplifying circuit layout. Consider the SMT form factor for automated assembly processes and space-constrained applications.

Part Context

This part belongs to Mini-Circuits' XHF series of reflectionless filters, which are engineered to address common issues associated with traditional reactive filters. The series covers various frequency bands, providing engineers with standardized solutions for signal conditioning in microwave and millimeter-wave applications.

Replacement Considerations

Direct substitutes include other Mini-Circuits reflectionless high-pass filters with similar cutoff frequencies, such as those in the VXHF series. Verify that any replacement maintains the same 50 Ohm impedance and SMT package dimensions to ensure compatibility with existing PCB layouts.
