KAT-0+

Overview

The KAT-0+ is a fixed attenuator fabricated using a GaAs MMIC process, operating from DC to 43.5 GHz. It provides 0 dB attenuation with a 50 Ohm impedance and handles 2 W of power. The device features an excellent typical VSWR of 1.3:1 and is housed in a compact 2x2 mm surface-mount package.

Feature Summary

• Absorptive fixed attenuator design utilizing reliable GaAs MMIC technology
• Operates across a super bandwidth range from DC to 43.5 GHz
• High power handling capability rated at 2 Watts
• Compact 2x2 mm surface-mount footprint

Applications

• DC to millimeter-wave signal conditioning
• RF test and measurement equipment
• Microwave circuit interconnects

Procurement Notes

Verify the specific datasheet version and manufacturer documentation for the KAT-0+ model to ensure compliance with required frequency ranges and power ratings. Confirm that the 0 dB specification aligns with system requirements for direct signal routing or impedance matching applications without unintended insertion loss deviations.

Selection Notes

Select this component when a broadband solution from DC to 43.5 GHz is required within a minimal footprint. The 2W power rating supports high-power environments, while the 0 dB value indicates its use for impedance matching or isolation rather than signal reduction. Ensure the 50 Ohm system impedance matches the application design.

Part Context

Mini-Circuits manufactures the KAT-0+ as part of its microwave precision line. This series utilizes GaAs MMIC processes to deliver consistent performance across wide frequency bands. The component serves as a passive element for maintaining signal integrity in high-frequency circuits.

Replacement Considerations

Consult Mini-Circuits official documentation for verified substitute part numbers. Cross-reference specifications such as frequency range, power handling, and package dimensions to ensure functional equivalence.
