FMAT7440N-70

Attenuators Overview

The FMAT7440N-70 is a rotary step attenuator manufactured by Fairview Microwave, designed for signal management in RF systems. It provides a total attenuation range of 0 to 70 dB with precise 1 dB step increments. The component utilizes N-type female connectors on both ends and operates effectively up to a maximum frequency of 6 GHz. It is rated for a power handling capacity of 2 Watts and features a rotary dial interface for manual adjustment.

Attenuators Feature Summary

• Rotary dial control mechanism for manual attenuation adjustment
• High precision 1 dB step resolution across the full range
• Robust N-type female connector interface for secure integration

Attenuators Applications

• RF test and measurement equipment calibration
• Signal level adjustment in communication systems
• Laboratory experimental setups requiring variable attenuation

Attenuators Procurement Notes

Verify the specific datasheet version for updated electrical parameters before integration. Confirm that the N-type female connector compatibility matches existing system interfaces. Ensure the 2 Watt power rating aligns with operational signal levels to prevent component damage. Check environmental specifications against deployment conditions.

Attenuators Selection Notes

Select this model when fixed attenuation is insufficient and precise manual control is required. The N-type interface suits general-purpose RF applications up to 6 GHz. Consider the rotary form factor for benchtop use rather than automated inline systems. Evaluate the 70 dB range against maximum required signal reduction needs.

Attenuators Part Context

This component belongs to the Fairview Microwave attenuator series, specifically engineered for interconnect applications. It serves as a passive RF device used to reduce signal amplitude without introducing significant distortion. The design prioritizes stability and repeatability in laboratory and industrial environments.

Attenuators Replacement Considerations

Direct substitutes include models with identical N-type female interfaces and comparable attenuation ranges. Verify frequency limits and power ratings match or exceed original requirements. Alternative rotary step attenuators from other manufacturers may require mechanical adaptation.
