FMAT7463-3

Attenuators Overview

The FMAT7463-3 is a fixed attenuator from Fairview Microwave designed for signal reduction in RF systems. It features SMA male (plug) to SMA female (jack) connectors, providing a nominal attenuation of 3 dB across a frequency range of 0 Hz to 12.4 GHz. The component operates at a 50 Ohm impedance and is rated for 10 Watts of power handling. Constructed with a brass nickel body, it maintains a VSWR of 1.35:1 and functions within a temperature range of -55°C to +125°C.

Attenuators Feature Summary

• Provides precise 3 dB signal attenuation for RF applications
• Operates effectively up to 12.4 GHz frequency range
• Supports high power handling capacity of 10 Watts
• Ensures stable signal transmission with low VSWR

Attenuators Applications

• RF test and measurement setups requiring signal reduction
• Communication systems needing precise gain control
• Laboratory environments for circuit characterization
• Defense and aerospace electronic subsystems

Attenuators Procurement Notes

Verify the specific datasheet version for the FMAT7463-3 to confirm mechanical dimensions and material specifications. Ensure that the SMA connector polarity matches the system requirements. Check for RoHS compliance status if environmental regulations apply to the deployment environment. Confirm the power rating aligns with peak operational loads rather than just average levels.

Attenuators Selection Notes

Select this model when a 3 dB attenuation value is required within the 12.4 GHz bandwidth. The 10 Watt power rating makes it suitable for higher power applications compared to standard 1 Watt variants. The SMA interface ensures compatibility with common RF infrastructure. Consider the brass nickel construction for durability in demanding environments.

Attenuators Part Context

This component belongs to the FMAT series of connectorized attenuators manufactured by Fairview Microwave. These devices are engineered to provide reliable signal attenuation in coaxial RF circuits. The series offers various attenuation values and connector types to suit different system architectures and frequency requirements.

Attenuators Replacement Considerations

Direct substitutes include models with identical 3 dB attenuation, SMA interfaces, and 12.4 GHz frequency limits. Verify power ratings match or exceed the 10 Watt requirement. Ensure VSWR specifications remain within acceptable limits for the application.
