UNAT-3A+

Overview

The UNAT-3A+ is a fixed attenuator from Mini-Circuits designed for RF and microwave applications. It provides a nominal attenuation of 3 dB across a frequency range from DC to 6000 MHz. The component features N-type connectors and operates within a 50 Ohm impedance system. It is rated for a maximum power handling capacity of 2 Watts. The device utilizes the FF779 case style, ensuring reliable performance in inline module configurations.

Feature Summary

• Provides precise 3 dB signal attenuation with excellent flatness across the operational bandwidth
• Supports continuous wave power handling up to 2 Watts for robust signal management
• Features N-type connectors for secure and standardized interconnection in RF systems

Applications

• Signal level adjustment in RF test and measurement setups
• Impedance matching and isolation in communication transceivers
• Attenuation stages in satellite communication ground stations

Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update performance graphs or mechanical dimensions over time. Confirm that the N-type connector gender and interface requirements match your system design. Ensure the 2W power rating aligns with your peak signal levels to prevent damage. Check for any recent supply chain notifications regarding lead times or production cycles directly from the manufacturer.

Selection Notes

Select this model when a fixed 3 dB reduction is required between DC and 6 GHz. Consider the FF779 form factor for space-constrained inline installations. Verify that the N-type interface compatibility exists with adjacent components. Evaluate thermal management needs based on the 2W power limit and expected duty cycle in the target application environment.

Part Context

This component belongs to the UNAT-A series of fixed attenuators manufactured by Mini-Circuits. The series is characterized by operation from DC to 6000 MHz with consistent attenuation flatness. The UNAT-3A+ represents the 3 dB variant within this lineup, offering a standard attenuation value for common RF circuit requirements.

Replacement Considerations

Direct substitutes include other Mini-Circuits models such as UNAT-1A+, UNAT-2A+, UNAT-4A+, and UNAT-5A+ for different attenuation values. Cross-manufacturer replacements require matching the 3 dB attenuation, 50 Ohm impedance, DC-6 GHz range, and N-type connector interface.
