KAT-5+

Overview

The KAT-5+ is an absorptive fixed attenuator fabricated using a reliable GaAs MMIC process. It operates from DC to 43.5 GHz with a nominal attenuation of 5 dB and a 50 Ohm impedance. The device features a 6-TDFN exposed pad package, supporting operation between -40°C and +85°C. It achieves a maximum VSWR of 1.4 and handles up to 1.4W of power.

Feature Summary

• Utilizes highly reliable GaAs MMIC fabrication for consistent performance
• Provides wideband operation extending from DC to 43.5 GHz
• Features an absorptive design with internal termination

Applications

• RF signal level control in high-frequency circuits
• Impedance matching in microwave test setups
• Signal conditioning in satellite communication systems

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm electrical parameters such as attenuation tolerance and frequency range. Ensure the 6-TDFN package dimensions align with your PCB layout requirements. Cross-reference the operating temperature range and power handling capabilities against your system's thermal and RF constraints before finalizing procurement.

Selection Notes

Select this component when a wide bandwidth up to 43.5 GHz is required alongside precise 5 dB attenuation. The GaAs MMIC technology ensures repeatability suitable for demanding RF applications. Consider the exposed pad package for thermal management and mounting stability in compact designs requiring high-frequency performance.
