FMAT7448-10

Attenuators Overview

The FMAT7448-10 is a fixed DC bias attenuator manufactured by Fairview Microwave, designed for RF applications up to 3 GHz. It provides a nominal attenuation of 10 dB with a tolerance of ±2.5 dB. The component features N-type male (plug) to N-type female (jack) connectors and operates at a system impedance of 50 Ohms. It is rated for a maximum input power of 2 Watts CW. Key electrical performance metrics include a maximum Voltage Standing Wave Ratio (VSWR) of 1.35:1 and a maximum DC bias current of 100 mA. The unit utilizes a brass tri-metal body construction.

Attenuators Feature Summary

• In-line resistive PI attenuator pad design
• DC bias functionality for active circuit integration
• Brass tri-metal body construction for durability

Attenuators Applications

• RF signal level control in test and measurement equipment
• Integration into active microwave circuits requiring DC bias
• Signal conditioning in communication systems operating up to 3 GHz

Attenuators Procurement Notes

Verify the connector gender configuration matches the specific application requirements, as N-type male to female configurations are standard but must be confirmed against schematic diagrams. Ensure that the DC bias current limit of 100 mA is not exceeded during operation to prevent component damage. Confirm that the 2 Watt power rating aligns with the maximum expected signal levels in the target circuit environment prior to deployment.

Attenuators Selection Notes

Select this component when a fixed 10 dB attenuation value is required within a 50 Ohm system architecture. The choice is appropriate for designs necessitating DC bias capability through the attenuator path, distinguishing it from standard passive fixed attenuators. Consider the physical size and brass tri-metal housing if thermal management or mechanical robustness is a priority in the installation environment.

Attenuators Part Context

This part belongs to the Fairview Microwave connectorized attenuator product line, specifically categorized under DC bias attenuators. It serves as a specialized interconnect solution that combines signal attenuation with DC power delivery capabilities. The model number indicates a 10 dB attenuation value within the FMAT series, which is engineered for reliable performance in high-frequency RF environments.

Attenuators Replacement Considerations

Direct substitutes may include other 10 dB N-type DC bias attenuators from different manufacturers, provided they match the 50 Ohm impedance, 3 GHz frequency range, and 2 Watt power rating. Verify that alternative components maintain the same VSWR specifications and DC bias current limits to ensure circuit compatibility.
