QAT-9+

Attenuators Overview

The QAT-9+ is a fixed RF attenuator from Mini-Circuits, providing 9 dB of attenuation. It operates over a frequency range of 0 Hz to 50 GHz with a nominal impedance of 50 Ohms. The device is designed for surface-mount applications in a 6-TDFN exposed pad package. It can handle an input power of up to 1.1W, with some sources indicating capabilities up to 2W. The component utilizes a GaAs MMIC IPD process for reliable performance.

Attenuators Procurement Notes

Verify the specific ordering suffix against official Mini-Circuits documentation to ensure correct specifications. Confirm that the requested part matches the required attenuation value and package type. Check for any variations in power handling ratings between different datasheet versions or distributor listings. Ensure compliance with RoHS status requirements if applicable to your project constraints.

Attenuators Selection Notes

Select this component when a fixed 9 dB attenuation is required at frequencies up to 50 GHz. Consider the 6-TDFN package for space-constrained PCB layouts. Evaluate the 1.1W power handling capability against system signal levels. Verify impedance matching requirements for 50 Ohm systems before integration into the design.

Attenuators Part Context

The QAT-9+ belongs to the QAT series of fixed attenuators manufactured by Mini-Circuits. This series offers various attenuation values while maintaining consistent performance characteristics across the frequency spectrum. The components are designed for use in high-frequency applications requiring precise signal level control.

Attenuators Replacement Considerations

Consult Mini-Circuits official documentation for direct substitute part numbers within the QAT series. Verify that alternative models match the 9 dB attenuation, 50 Ohm impedance, and 6-TDFN package requirements. Cross-reference pin configurations and thermal pad designs to ensure compatibility.
