KAT-9+

Overview

The KAT-9+ is a fixed attenuator manufactured by Mini-Circuits, utilizing a GaAs MMIC process. It provides an attenuation of 9.3 dB across a frequency range from 0 Hz to 43.5 GHz. The component operates within a 50 Ohm impedance system and features a maximum VSWR of 1.9. It supports a power rating of 1.1 W and functions in temperatures between -40 C and +85 C. The device is housed in an MCLP-6 surface-mount package.

Feature Summary

• Absorptive design fabricated using reliable GaAs MMIC technology
• Broadband operation extending from DC to millimeter-wave frequencies
• Fixed attenuation value for consistent signal reduction

Applications

• RF and microwave circuit signal level control
• Impedance matching in high-frequency transmission lines
• Test and measurement equipment signal conditioning

Procurement Notes

Verify the specific part number suffix against official Mini-Circuits documentation to ensure correct configuration. Confirm that the MCLP-6 package style aligns with your PCB layout requirements. Check the latest datasheet for any updates on operating temperature ranges or power ratings. Ensure compatibility with your manufacturing process for surface-mount assembly. Validate all electrical parameters against your system specifications before finalizing procurement.

Selection Notes

Select this component when a fixed attenuation value is required in broadband applications up to 43.5 GHz. Consider the GaAs MMIC construction for reliability in harsh environments. Evaluate the 50 Ohm impedance match for integration into standard RF systems. Assess the thermal performance within the specified operating temperature range. Review the physical dimensions of the MCLP-6 package for space constraints.

Part Context
