KAT-6+

Overview

The KAT-6+ is a fixed attenuator from Mini-Circuits, fabricated using a reliable GaAs MMIC process. It operates from DC to 43.5 GHz with a nominal attenuation of 6.1 dB. The device features a 50 Ohm impedance and supports up to 1.6 W power rating. It utilizes an MCLP-6 surface-mount package. Electrical specifications include a maximum VSWR of 1.7. The component functions within a temperature range of -40 C to +85 C. It is available in Cut Tape, Reel, and MouseReel packaging formats.

Feature Summary

• Absorptive design utilizing GaAs MMIC technology for high reliability
• Wideband operation extending from DC to 43.5 GHz
• Compact MCLP-6 surface-mount package suitable for automated assembly

Applications

• RF signal level control in microwave systems
• Impedance matching in high-frequency test equipment
• Signal conditioning in wireless communication infrastructure

Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to ensure correct electrical tolerances and pinout configuration. Confirm that the required operating frequency range aligns with the 43.5 GHz upper limit. Check thermal management requirements relative to the 1.6 W power rating. Ensure the MCLP-6 footprint matches the PCB layout constraints. Validate RoHS compliance status through current manufacturer declarations.

Selection Notes

Select this component when a fixed 6 dB attenuation is required at frequencies approaching 40 GHz. The GaAs MMIC construction offers consistency across production batches. Consider the MCLP-6 package size for space-constrained designs. Evaluate the VSWR specification against system return loss requirements. Compare performance metrics with alternative attenuators if broader bandwidth or different attenuation values are needed.

Part Context

The KAT-6+ belongs to the KAT series of fixed attenuators produced by Mini-Circuits. This series focuses on providing stable attenuation values using monolithic microwave integrated circuit technology. The KAT series components are designed for applications requiring precise signal reduction without reflection, supporting both commercial and industrial RF environments.

Replacement Considerations

Consult Mini-Circuits official substitution guides for direct replacements. Verify compatibility of interface standards and mounting footprints. Ensure equivalent electrical performance in terms of attenuation accuracy and frequency response.
