FMAT7000

Overview

The FMAT7000 is a rotary step attenuator manufactured by Fairview Microwave, designed for high-precision signal control in RF systems. It provides an attenuation range of 0 to 60 dB with 10 dB steps, rated for up to 2 Watts power handling and operating frequencies up to 6 GHz. The unit features N-type female connectors on both input and output ports, ensuring compatibility with standard coaxial infrastructure. Constructed for durability, it includes a heatsink design suitable for medium-power applications. Operating temperatures extend up to +70°C, and the device draws approximately 1 A of supply current during operation.

Feature Summary

• Rotary mechanical step adjustment mechanism for precise attenuation control
• N-type female interface connectors for standardized RF integration
• Integrated heatsink structure for thermal management at rated power levels

Applications

• Automated test and measurement equipment requiring variable signal levels
• System-level RF testing environments needing stable attenuation steps
• Remote site communication systems utilizing controlled signal reduction

Procurement Notes

Verify the specific datasheet version for the FMAT7000 to confirm connector polarity and mechanical dimensions prior to integration. Ensure that the system power supply can provide the required 1 A operating current. Confirm that the N-type female interfaces align with existing cable assemblies. Check thermal requirements against the +70°C maximum operating temperature limit to prevent overheating during continuous use.

Selection Notes

Select this component when fixed-step attenuation between 0 and 60 dB is required in the 6 GHz frequency range. The N-type interface dictates compatibility with larger coaxial systems rather than miniature connectors. Consider the physical size and weight implications due to the internal rotary mechanism and heatsink. Verify that the 2 Watt power rating meets the peak signal levels present in the application path.

Part Context

This model belongs to the Fairview Microwave attenuator series, specifically engineered as a connectorized interconnect component. It serves as a passive RF control element within broader microwave and radio frequency circuit architectures. The product is categorized under connectorized attenuators, distinct from fixed or digital programmable variants, offering manual rotary adjustment capabilities for laboratory and industrial settings.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult the manufacturer directly for cross-reference information regarding equivalent rotary step attenuators with matching N-type interfaces and 60 dB ranges.
