SA75DFDM50W-50

Attenuators Overview

The SA75DFDM50W-50 is a fixed RF attenuator manufactured by Fairview Microwave, designed for high-power applications up to 300 Watts. It provides a nominal attenuation of 50 dB with a maximum frequency range extending to 3 GHz. The component features a directional configuration with 7/16 Male (Plug) connectors on both ends. It incorporates a heatsink body to manage thermal loads and maintains a Voltage Standing Wave Ratio (VSWR) of 1.4. The unit operates from DC to 3 GHz with a 50 Ohm impedance.

Attenuators Feature Summary

• High power handling capability rated at 300 Watts for robust operation in demanding environments.
• Directional design ensures precise signal attenuation within the specified frequency bandwidth.
• Integrated heatsink body facilitates efficient thermal dissipation during continuous high-power usage.

Attenuators Applications

• High-power RF signal testing and measurement systems
• Base station transmitter line conditioning
• Industrial heating and plasma generation equipment

Attenuators Procurement Notes

Verify connector gender and orientation against system requirements, as this model specifies Male-to-Male configuration. Confirm thermal management needs align with the integrated heatsink design for sustained 300 Watt operation. Ensure frequency requirements do not exceed the 3 GHz upper limit. Cross-reference datasheet specifications for VSWR and attenuation tolerance to guarantee compatibility with sensitive measurement instrumentation.

Attenuators Selection Notes

Select this model when high power handling is critical, distinguishing it from lower-rated variants like the 50 Watt SA75DFDM50W-50. Consider the 7/16 interface standard for compatibility with large-diameter coaxial systems. Evaluate the directional nature against bidirectional signal paths. Compare thermal performance against ambient conditions to ensure the heatsink suffices without external cooling.

Attenuators Part Context

This part belongs to Fairview Microwave's connectorized attenuator series, specifically engineered for high-power RF applications. It utilizes Times Microwave System components for consistent performance. The product line emphasizes durability and precision in industrial and telecommunications sectors requiring stable signal reduction under heavy load conditions.

Attenuators Replacement Considerations
