UNAT-1A+

Overview

The UNAT-1A+ is a coaxial fixed attenuator manufactured by Mini-Circuits, designed for RF and microwave applications. It provides a nominal attenuation value of 1 dB with a tolerance of 0.3 dB across a frequency range from DC to 6 GHz. The component operates at a power rating of 2 Watts (30 dBm) and features a characteristic impedance of 50 Ohms. It utilizes N-Type connectors in an in-line module configuration, suitable for environments ranging from -45°C to +100°C.

Feature Summary

• Fixed attenuation performance with excellent flatness across the operational bandwidth
• Robust construction utilizing N-Type connectors for reliable signal transmission
• Wide operating temperature range supporting diverse environmental conditions

Applications

• RF signal level adjustment in test and measurement equipment
• Impedance matching and signal conditioning in communication systems
• Attenuation insertion in microwave circuit designs

Procurement Notes

Verify the specific datasheet version and connector orientation details before procurement. Confirm that the N-Type interface matches your system requirements. Ensure the 2W power rating and 50 Ohm impedance align with your circuit design specifications. Check for RoHS and REACH compliance documentation if required for your regulatory standards.

Selection Notes

Select this component when a precise 1 dB reduction is needed within a 50 Ohm system up to 6 GHz. Consider the N-Type connector compatibility and the 2W power handling capacity. Evaluate the thermal operating limits against your application's environmental constraints. This model is suitable where stable attenuation flatness is critical for signal integrity.

Part Context

The UNAT-1A+ belongs to the UNAT-A series of fixed attenuators from Mini-Circuits. This series is characterized by its ability to maintain consistent attenuation values over a broad frequency spectrum from DC to 6000 MHz. The components are engineered for high reliability in demanding RF environments.

Replacement Considerations

Consult official Mini-Circuits documentation for verified substitute part numbers within the UNAT series or compatible fixed attenuator lines. Ensure any replacement maintains identical impedance, connector type, and frequency range specifications.
