UNAT-20A+

Overview

The Mini-Circuits UNAT-20A+ is a fixed RF attenuator designed for in-line applications within the DC to 6 GHz frequency range. It provides a nominal attenuation of 20 dB with a tolerance of ±0.3 dB, ensuring excellent flatness across its operational bandwidth. The component features N-Type connectors and operates at a 50 Ohm impedance. It supports a maximum power rating of 800 mW and functions reliably within an operating temperature range starting from -45°C.

Feature Summary

• Fixed attenuation value of 20 dB with high precision
• Wideband operation from DC to 6 GHz
• Robust N-Type connectorized design for in-line integration

Applications

• RF signal level control in test and measurement equipment
• Attenuation stages in wireless communication systems
• Signal conditioning in microwave circuit assemblies

Procurement Notes

Verify the specific part number suffix against official Mini-Circuits documentation to confirm RoHS compliance status and connector type accuracy. Ensure that the required attenuation tolerance and power handling capabilities align with the system's thermal and electrical constraints before finalizing procurement orders.

Selection Notes

Select this model when a precise 20 dB reduction is required over a broad frequency spectrum up to 6 GHz. Consider the 800 mW power rating and N-Type interface compatibility with existing cabling infrastructure. Evaluate the -45°C minimum operating temperature limit against environmental conditions.

Part Context

This component belongs to the UNAT-A series of fixed attenuators manufactured by Mini-Circuits. The series is characterized by excellent attenuation flatness and covers a frequency range from DC to 6000 MHz. These units are engineered for stable performance in demanding RF environments requiring reliable signal attenuation.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified equivalent models. Cross-reference specifications such as attenuation value, frequency range, and connector type to ensure functional compatibility without altering system performance characteristics.
