FMAT7511-3

Attenuators Overview

The FMAT7511-3 is a fixed attenuator manufactured by Fairview Microwave, designed for RF signal management. It provides a nominal attenuation of 3 dB with an impedance of 50 Ohms. The component utilizes TNC connectors, featuring a male plug on one end and a female jack on the other. It operates effectively up to a maximum frequency of 3 GHz. The device is rated for a power handling capacity of 2 Watts. Constructed with a brass body and tri-metal finish, it ensures durability in various environments. The unit weighs approximately 43 grams and measures 58.9 mm in length.

Attenuators Feature Summary

• Provides precise 3 dB signal attenuation for RF circuitry
• Features robust brass construction with tri-metal plating
• Utilizes standard TNC connector interface for compatibility
• Supports operation up to 3 GHz frequency range

Attenuators Applications

• RF test and measurement equipment signal conditioning
• Wireless communication system power level adjustment
• Laboratory instrumentation signal attenuation
• Military and aerospace RF subsystem integration

Attenuators Procurement Notes

Verify the specific connector gender configuration (male-to-female) against schematic requirements before ordering. Confirm that the 2 Watt power rating aligns with the maximum expected signal levels in the target application. Ensure the operating temperature range meets environmental specifications. Check for RoHS compliance documentation if required by project standards. Validate that the 50 Ohm impedance matches the system design to prevent mismatch losses.

Attenuators Selection Notes

Select this component when a fixed 3 dB reduction is required in a 50 Ohm system using TNC interfaces. Consider the physical dimensions and weight constraints for installation space. Evaluate the thermal dissipation capabilities given the 2 Watt power limit. Compare against variable attenuators if adjustable signal control is needed instead. Ensure the frequency response up to 3 GHz covers the operational bandwidth without significant insertion loss variation.

Attenuators Part Context

This part belongs to Fairview Microwave's line of connectorized attenuators, specifically designed for reliable RF signal management. It complements their broader portfolio of RF cable assemblies and antennas. The product series emphasizes durability and consistent performance in demanding environments.
