UNAT-4A+

Overview

The UNAT-4A+ is a fixed attenuator manufactured by Mini-Circuits, designed for RF applications. It provides a nominal attenuation of 4 dB with an operating frequency range from DC to 6000 MHz (6 GHz). The component features a characteristic impedance of 50 Ohms and utilizes N-Type connectors for in-line module integration. It is rated for a power handling capacity of 1.7 Watts and complies with RoHS and REACH standards.

Feature Summary

• Provides fixed 4 dB signal attenuation across a wide frequency spectrum
• Utilizes robust N-Type connector interface for reliable in-line connection
• Operates effectively from DC up to 6000 MHz
• Maintains 50 Ohm system impedance compatibility

Applications

• RF signal level adjustment in communication systems
• Test and measurement equipment setups
• Wireless infrastructure signal conditioning

Procurement Notes

Verify the specific datasheet version and compliance documentation upon ordering. Confirm that the N-Type connector orientation matches the system requirements. Ensure the operating environment stays within the specified power and temperature limits to maintain performance integrity and longevity of the component.

Selection Notes

Select this model when a precise 4 dB reduction is required at frequencies up to 6 GHz. The N-Type interface suits high-power applications needing secure connections. Consider the 1.7W power rating against system load. This part replaces the older UNAT-4+ variant while maintaining similar electrical specifications.

Part Context

This component belongs to Mini-Circuits' UNAT series of fixed attenuators. It serves as a direct replacement for the legacy UNAT-4+ model. The series is characterized by stable attenuation values and durable construction suitable for demanding RF environments. It fits into standard in-line module configurations for easy integration.

Replacement Considerations

The UNAT-4A+ officially replaces the UNAT-4+ part number. Verify connector gender and mating compatibility when substituting. Electrical parameters remain consistent between the original and updated versions.
