SA4F75-01

Attenuators Overview

The SA4F75-01 is a fixed attenuator manufactured by Fairview Microwave, designed for signal conditioning in RF systems. It features F-type connectors with a male plug on one side and a female jack on the other. The component provides a nominal attenuation of 1 dB with a tolerance of ±0.5 dB across a frequency range from DC to 4 GHz. It operates at a maximum continuous wave power of 0.25 Watts and maintains a Voltage Standing Wave Ratio (VSWR) of less than 1.30:1.

Attenuators Feature Summary

• Provides precise 1 dB signal attenuation within a wide DC to 4 GHz bandwidth
• Utilizes standard F-type male-to-female connector interface for easy integration
• Maintains low VSWR below 1.30:1 to ensure minimal signal reflection
• Engineered for stable performance under 0.25 Watts continuous wave power

Attenuators Applications

• RF instrumentation testing setups
• Signal level adjustment in communication circuits
• Attenuation requirements in microwave measurement systems

Attenuators Procurement Notes

Verify the specific manufacturer part number against official datasheets to confirm electrical specifications such as attenuation value, frequency range, and power rating. Ensure compatibility with existing F-type connector interfaces. Check for updated product revisions or alternative suffixes that may indicate minor physical or material changes without altering core functionality.

Attenuators Selection Notes

Select this component when a low-value fixed attenuation is required in the sub-4 GHz spectrum. The F-type interface makes it suitable for legacy or specific coaxial applications where BNC or SMA are not viable. Consider the 0.25 Watt power limit for high-power environments and verify impedance matching requirements for the specific system design.

Attenuators Part Context

This part belongs to Fairview Microwave's line of fixed attenuators, which are passive components used to reduce signal strength without distorting the waveform. These devices are essential for protecting sensitive equipment from high-power signals and for calibrating measurement instruments. The F-type connector variant is specifically tailored for applications requiring this standardized interface.

Attenuators Replacement Considerations

Direct substitutes include models with identical 1 dB attenuation, F-type connectors, and similar frequency/power ratings. Verify that any replacement maintains the <1.30:1 VSWR specification and DC to 4 GHz operational range to ensure circuit performance consistency.
