FMAT7463-20

Attenuators Overview

The FMAT7463-20 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications. It provides a nominal attenuation of 20 dB with a frequency range extending from DC to 12.4 GHz. The device features SMA male (plug) to SMA female (jack) connectors and is rated for 10 watts of power handling. Constructed with a black aluminum body, it maintains a VSWR of 1.3:1 and operates within a 50 Ohm impedance system.

Attenuators Feature Summary

• Unidirectional signal attenuation capability
• High power handling rating of 10 watts
• Broadband operation up to 12.4 GHz
• Durable black aluminum housing

Attenuators Applications

• RF signal level reduction in test setups
• Impedance matching in microwave circuits
• Protection of sensitive receiver inputs

Attenuators Procurement Notes

Verify the specific datasheet version for the FMAT7463-20 to confirm unidirectional characteristics and 10W power rating. Ensure SMA connector compatibility with existing infrastructure. Check for any specific handling requirements due to the high power rating. Confirm the frequency range meets the 12.4 GHz requirement. Validate the 1.3:1 VSWR specification against system tolerance limits.

Attenuators Selection Notes

Select this component when a 20 dB fixed attenuation value is required at frequencies up to 12.4 GHz. The 10W power rating distinguishes it from lower-power variants like the FMAT7466 series. The unidirectional nature may influence placement in the signal chain. The SMA interface ensures compatibility with standard coaxial systems. Consider the aluminum body for thermal management in high-power scenarios.

Attenuators Part Context

This part belongs to Fairview Microwave's line of connectorized attenuators. It shares the SMA interface and general form factor with other models but differs in attenuation value, power rating, and directional properties. It serves as a passive component for managing signal strength in RF environments.

Attenuators Replacement Considerations

The FMAT7466-20 is a similar 20 dB attenuator but has a lower 2W power rating and stainless steel body. Verify if the higher power handling of the FMAT7463-20 is necessary. The FMAT7463-20 is unidirectional, whereas some alternatives may be bidirectional.
