XBF-163+

Overview

The Mini-Circuits XBF-163+ is a four-section GaAs MMIC reflectionless bandpass filter designed for high-performance RF applications. It operates with a center frequency of 16 GHz and provides a bandwidth of 1 GHz. The component features an insertion loss of 6 dB and maintains a 50 Ohm impedance. Packaged in a compact 24-VFQFN surface-mount enclosure measuring 4.00mm x 4.00mm, it utilizes a novel topology to absorb stopband signals internally, ensuring ultra-high rejection up to 50 dB.

Feature Summary

• Four-section GaAs MMIC reflectionless design
• Internal absorption of stopband signals
• Ultra-high stopband rejection up to 50 dB

Applications

• S-band frequency upconverter assemblies
• Microwave communication systems
• RF signal processing circuits

Procurement Notes

Verify the specific suffix against official Mini-Circuits documentation to confirm exact electrical characteristics and package variations. Ensure compatibility with 50 Ohm system impedance requirements. Confirm RoHS compliance status and moisture sensitivity level prior to integration into production workflows.

Selection Notes

Select this component when high stopband rejection and internal termination are required to prevent signal reflections. The 16 GHz center frequency suits S-band applications. Evaluate the 6 dB insertion loss against system noise budget constraints. The 24-VFQFN package facilitates surface-mount assembly in compact designs.

Part Context

The XBF-163+ belongs to the Mini-Circuits XBF-Series, which comprises GaAs MMIC reflectionless filters. This series is engineered to provide superior performance by terminating stopband energy internally rather than reflecting it, thereby improving stability in sensitive RF front-end architectures.

Replacement Considerations

The XBF-163-D is documented as a die variant of this product family. Verify if bare die implementation meets mechanical and thermal requirements before considering substitution.
