UNAT-9A+

Overview

The UNAT-9A+ is a fixed attenuator manufactured by Mini-Circuits, designed for operation from DC to 6000 MHz. It provides a nominal attenuation of 9 dB with an accuracy tolerance of 0.3 dB. The component features N-type connectors and maintains a characteristic impedance of 50 Ohms. It has a maximum power rating of 1.1 W and a maximum VSWR of 1.5. The unit weighs 72.5 grams and utilizes Si technology within the FF779 case style.

Feature Summary

• Fixed value absorptive MMIC design utilizing highly repetitive IPD process technology
• N-type connector interface for in-line module integration
• RoHS compliant construction

Applications

• RF signal level control in communication systems
• Test and measurement equipment calibration
• Microwave circuit attenuation requirements

Procurement Notes

Verify the specific datasheet version for the UNAT-9A+ to confirm connector type and mechanical dimensions. Ensure the application environment supports the specified 1.1 W power rating and 6 GHz frequency range. Cross-reference the 50 Ohm impedance requirement with system components to prevent mismatch issues during procurement validation.

Selection Notes

Select this component when a precise 9 dB attenuation is required across a wide bandwidth up to 6 GHz. The N-type connector facilitates robust interconnection in high-frequency applications. Consider the 1.1 W power handling capability for signal management tasks where higher dissipation is necessary compared to lower-power variants.

Part Context

The UNAT-9A+ belongs to Mini-Circuits' line of fixed attenuators, specifically the UNAT series. It is distinct from similar models like the YAT-9A+ primarily through its connector configuration and specific package designation. This part represents a standard solution for broadband RF attenuation needs within the company's product catalog.

Replacement Considerations

Direct substitutes include other Mini-Circuits fixed attenuators with matching 9 dB attenuation and N-type interfaces, such as the UNAT-9+. Verify that alternative parts maintain the same 50 Ohm impedance and frequency range to ensure functional compatibility without redesigning the host circuit.
