Overview
The XBF-183+ is a reflectionless band pass filter MMIC designed for the K-band spectrum. It operates within a frequency range of 17500 to 18500 MHz, providing a 1 GHz bandwidth centered at 18 GHz. The component maintains a standard 50Ω impedance and features an insertion loss of 5.8 dB. It is housed in a compact 24-VFQFN package with an exposed pad, suitable for high-frequency signal conditioning applications requiring minimal reflection.
Feature Summary
- Reflectionless architecture minimizes signal reflections across the passband
- Integrated MMIC design for compact signal conditioning
- Optimized for K-band frequency operations
Applications
- K-band communication systems
- Satellite communications upconverters
- Microwave test and measurement equipment
Procurement Notes
Verify the specific suffix designation against official Mini-Circuits documentation to ensure correct configuration. Confirm that the 24-VFQFN package dimensions align with your PCB layout requirements. Cross-reference the electrical specifications with your system's impedance and frequency constraints before finalizing procurement decisions.
Selection Notes
Select this component when low reflection is critical for system stability in the 17.5 to 18.5 GHz range. The integrated MMIC approach reduces board space compared to discrete solutions. Ensure thermal management strategies account for the exposed pad design typical of this package type.
Part Context
This part belongs to Mini-Circuits' reflectionless filter series, which utilizes internal termination to absorb out-of-band signals rather than reflecting them. This technology improves performance in cascaded stages by preventing standing waves. The XBF-183+ specifically targets the upper K-band frequencies for specialized RF applications.
FAQ
What is the primary advantage of the reflectionless design?
It absorbs out-of-band energy internally, preventing signal reflections that can destabilize upstream components.
Does the package include an exposed pad?
Yes, the 24-VFQFN package features an exposed pad for thermal dissipation and grounding.
