SA3SFF300W-03

Attenuators Overview

The SA3SFF300W-03 is a fixed attenuator manufactured by Fairview Microwave, designed for signal conditioning applications. It features SMA connectors with a jack-to-jack configuration, providing a nominal attenuation of 3 dB. The component operates within a frequency range extending up to 18 GHz and is rated for a maximum power handling capacity of 300 Watts. Key electrical specifications include a Voltage Standing Wave Ratio (VSWR) of 1.4. The unit utilizes a heatsink body construction to manage thermal loads effectively during high-power operation.

Attenuators Feature Summary

• Provides precise 3 dB fixed signal attenuation using SMA jack-to-jack interface connections.
• Engineered with a heatsink body design to support continuous operation at high power levels up to 300 Watts.
• Maintains stable impedance matching characterized by a VSWR of 1.4 across the operational bandwidth.

Attenuators Applications

• High-power RF test and measurement setups requiring precise signal level reduction.
• Integration into microwave communication systems operating within the specified frequency range.
• Signal conditioning in radar or electronic warfare equipment demanding robust thermal management.

Attenuators Procurement Notes

Verify the current product status as the listing indicates an obsolete classification. Confirm availability through authorized distributors or surplus channels, as standard manufacturing may have ceased. Ensure that the SMA jack-to-jack configuration meets specific system interface requirements before procurement. Cross-reference datasheet specifications against application needs to confirm compatibility with existing infrastructure.

Attenuators Selection Notes

Select this component when a fixed 3 dB attenuation is required in high-power environments. The 300 Watt rating distinguishes it from lower-power variants suitable for general laboratory use. The SMA connector type offers widespread compatibility but requires verification against mating hardware. Consider the heatsink body for applications involving sustained high-duty cycles where thermal dissipation is critical.

Attenuators Part Context

This model belongs to the Fairview Microwave series of connectorized attenuators. It shares the brand's focus on high-power handling capabilities, indicated by the '300W' designation in the part number. The SMA connector style aligns with common industry standards for frequencies up to 18 GHz. It represents a specialized solution for scenarios where standard attenuators would fail due to thermal limitations.

Attenuators Replacement Considerations

Due to the obsolete status, direct replacements may be limited. Evaluate equivalent models from Fairview Microwave with similar power ratings and connector types. Other manufacturers offering SMA fixed attenuators with comparable 300 Watt ratings should be considered. Verify that substitute components match the 1.4 VSWR and 18 GHz frequency limits to ensure system performance integrity.
