FMAT7487-5

Attenuators Overview

The FMAT7487-5 is a fixed RF attenuator manufactured by Fairview Microwave. It provides a nominal attenuation value of 5 dB across a frequency range of 0 Hz to 26.5 GHz. The component features SMA male-to-female in-line connections and maintains a 50 Ohm impedance. It is rated for a maximum power handling capacity of 2 Watts. The unit utilizes a single-row module package design.

Attenuators Feature Summary

• Provides precise 5 dB signal attenuation for RF circuitry
• Operates effectively from DC up to 26.5 GHz
• Connects via standard SMA male and female interfaces
• Handles continuous power loads up to 2 Watts

Attenuators Applications

• RF signal level adjustment in test and measurement setups
• Attenuation within wireless communication systems
• Signal conditioning in microwave instrumentation
• Integration into RF front-end modules requiring fixed loss

Attenuators Procurement Notes

Verify the specific datasheet version for the FMAT7487-5 to confirm current manufacturing status and detailed electrical tolerances. Ensure that the SMA connector gender and mating requirements align with the system interface. Confirm that the 2W power rating and 26.5 GHz frequency limit meet the operational demands of the intended application environment before finalizing procurement.

Attenuators Selection Notes

Select this component when a fixed 5 dB loss is required at frequencies extending to 26.5 GHz. The SMA interface offers broad compatibility with standard RF infrastructure. Consider the 2W power rating to ensure it exceeds the maximum expected signal power in the line. This model suits applications needing stable attenuation without variable adjustment capabilities.

Attenuators Part Context

This part belongs to the Fairview Microwave FMAT7487 series of connectorized attenuators. The series includes variants with different attenuation values, such as the FMAT7487-3 (3 dB) and FMAT7487-6 (6 dB). All models in this family share similar construction standards, utilizing SMA connectors and supporting operation up to 26.5 GHz with consistent 50 Ohm impedance characteristics.

Attenuators Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include Amphenol XMA part numbers 2682-6460-06 and 2682-6460-06-CRYO. These alternatives offer matching 6 dB specifications and SMA interfaces, though verification of exact 5 dB tolerance and power ratings against the original datasheet is required.
