KAT-20+

Overview

The KAT-20+ is an absorptive fixed attenuator fabricated using a GaAs MMIC process. It operates from DC to 43.5 GHz with a nominal attenuation of 20 dB. The device features a 50 Ohm impedance and utilizes an MCLP-6 surface-mount package. Key electrical specifications include a maximum VSWR of 1.9 and a power handling capability of 1.1 W. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes highly reliable GaAs MMIC fabrication for consistent performance
• Provides broadband operation extending from DC to 43.5 GHz
• Employs an absorptive design architecture

Applications

• Microwave signal conditioning
• RF test and measurement equipment
• Wireless communication systems

Procurement Notes

Verify the specific datasheet version for the KAT-20+ to confirm exact attenuation tolerances and pin configurations. Ensure the MCLP-6 footprint matches the target PCB layout. Confirm that the 1.1 W power rating aligns with system thermal requirements. Cross-reference the 43.5 GHz upper frequency limit against application needs.

Selection Notes

Select this component when a fixed 20 dB reduction is required across a wide microwave bandwidth. The GaAs MMIC technology ensures stability in high-frequency environments. Consider the MCLP-6 package size for space-constrained designs. Verify compatibility with 50 Ohm system impedance standards.

Part Context

The KAT-20+ belongs to the Mini-Circuits KAT series of MMIC attenuators. This series covers various attenuation values while maintaining similar form factors and broad frequency ranges. These devices are designed for integration into complex RF front-ends where precise signal level control is necessary without introducing significant reflection.

Replacement Considerations

Direct substitutes within the same series include KAT-10+, KAT-15+, and KAT-30+. For different attenuation values, verify that the MCLP-6 package and 43.5 GHz frequency response remain suitable for the specific circuit requirements.
