XHF-63M+

Overview

The XHF-63M+ is a two-section reflectionless high-pass filter from Mini-Circuits, designed for RF applications up to 86 GHz. It features a center frequency of 12.45 GHz and a bandwidth of 13.1 GHz. The component operates at a standard impedance of 50 Ohms with an insertion loss of 2.1 dB. It is housed in a compact 12-VQFN package with an exposed pad, suitable for surface mount technology.

Feature Summary

• Employs a novel reflectionless topology that absorbs and terminates stop-band signals internally
• Provides high isolation by preventing signal reflections back to the source
• Utilizes a compact 12-VQFN surface-mount package for efficient PCB integration

Applications

• RF front-end modules requiring minimal signal reflection
• Microwave communication systems operating above 12 GHz
• Test and measurement equipment needing precise high-pass filtering

Procurement Notes

Verify the specific suffix (e.g., +, D) against your design requirements, as variants like the die version differ in packaging. Confirm the 50-ohm impedance match with your system interface. Ensure the 12-VQFN footprint aligns with your PCB layout guidelines before finalizing procurement orders.

Selection Notes

Select this component when internal termination of reflected energy is critical to system stability. The two-section design offers a balance between size and performance. Consider the 2.1 dB insertion loss impact on overall link budget. The exposed pad requires proper thermal and electrical grounding during assembly.

Part Context

This part belongs to Mini-Circuits' X-Series of reflectionless filters, which utilize absorptive topologies instead of traditional reflective designs. This series addresses issues caused by signal reflections in high-frequency circuits, improving performance in sensitive RF environments compared to conventional filter technologies.

Replacement Considerations

The XHF-63M-D+ is the die version of this component. Verify if bare die or packaged form is required. No direct functional substitutes are listed; ensure compatibility with existing 50-ohm infrastructure.
