FMAT7488-40

Attenuators Overview

The FMAT7488-40 is a fixed attenuator manufactured by Fairview Microwave, designed for signal conditioning in RF systems. It provides a precise attenuation value of 40 dB across a frequency range extending from DC to 26.5 GHz. The component utilizes SMA connectors, featuring a male plug on one end and a female jack on the other. Constructed as a single-row module, it supports a power handling capacity of 2 watts and maintains a system impedance of 50 ohms.

Attenuators Procurement Notes

Verify the specific datasheet for the FMAT7488-40 to confirm mechanical dimensions and material specifications. Ensure compatibility with existing SMA interfaces in the design. Check manufacturer documentation for detailed electrical performance curves and thermal management requirements before integration into final assemblies.

Attenuators Selection Notes

Select this component when a high-isolation fixed attenuation of 40 dB is required at microwave frequencies up to 26.5 GHz. The SMA interface offers broad availability and ease of integration. Consider the 2-watt power rating to ensure safe operation within the system's power budget without exceeding thermal limits.

Attenuators Part Context

This part belongs to the Fairview Microwave series of fixed attenuators, which are essential passive components for managing signal strength in RF circuits. These devices are typically used to protect sensitive downstream components from high-power signals or to match impedance levels between different stages of an RF chain.

Attenuators Replacement Considerations

Publicly confirmed substitute part numbers include M3933/30-09N, M3933/30-09S, PE7487-4, R413304000, and R413804121. Verify that any replacement matches the 40 dB attenuation value, 50-ohm impedance, and SMA connector type.
