FMAT7520-1

Attenuators Overview

The FMAT7520-1 is a fixed RF attenuator manufactured by Fairview Microwave, designed for inline signal reduction in microwave systems. It operates within a frequency range of 0 Hz to 6 GHz and provides an attenuation value of 1 dB. The component features QMA male (plug) to QMA female (jack) connectors and maintains a 50 Ohm impedance throughout its operational bandwidth. Rated for 2 Watts of power handling, it utilizes a brass body with tri-metal plating to ensure durability and consistent performance in high-frequency applications.

Attenuators Feature Summary

• Provides precise 1 dB signal attenuation for RF circuitry
• Operates effectively from DC up to 6 GHz frequency range
• Features robust brass construction with tri-metal surface treatment

Attenuators Applications

• RF test and measurement equipment calibration
• Signal level adjustment in communication systems
• Impedance matching between 50 Ohm components

Attenuators Procurement Notes

Verify the specific model suffix to confirm the exact attenuation value, as the series includes variants with different dB ratings. Ensure connector compatibility with existing QMA interfaces in the system design. Confirm power rating requirements against peak signal levels to prevent damage. Check datasheet specifications for VSWR limits to maintain signal integrity within the 6 GHz operational band.

Attenuators Selection Notes

Select this component when a minimal 1 dB reduction is required at frequencies extending to 6 GHz. The QMA interface suits applications needing quick connection stability. Consider the 2 Watt power rating for moderate signal environments. The brass body offers mechanical strength suitable for repeated mating cycles in laboratory or industrial settings.

Attenuators Part Context

This part belongs to the FMAT7520 series of fixed attenuators from Fairview Microwave. The series includes various attenuation values such as 2 dB, 3 dB, 6 dB, 9 dB, and 20 dB, all sharing similar QMA connector types and 50 Ohm impedance characteristics. These components are engineered for reliable performance in broadband RF applications requiring stable attenuation across the specified frequency range.

Attenuators Replacement Considerations

Compatible substitutes include other FMAT7520 series variants like FMAT7520-2 or FMAT7520-6 if different attenuation values are acceptable. Ensure any replacement maintains the QMA male-to-female configuration and 50 Ohm impedance to preserve system connectivity and signal quality without modification.
