SA3DFF300W-10

Attenuators Overview

The SA3DFF300W-10 is a fixed attenuator manufactured by Fairview Microwave, designed for high-power RF applications up to 3 GHz. It features a 7/16 female (jack) to 7/16 female (jack) interface configuration. The component provides a nominal attenuation of 10 dB with a Voltage Standing Wave Ratio (VSWR) of 1.4. It is rated to handle continuous power levels up to 300 Watts and incorporates a heatsink body for thermal management. The unit operates within a frequency range of 0 Hz to 3 GHz and maintains a 50 Ohm impedance.

Attenuators Feature Summary

• High power handling capability rated at 300 Watts
• Integrated heatsink body for efficient thermal dissipation
• Directional design ensuring signal integrity
• Dual female 7/16 connector interface

Attenuators Applications

• High-power RF test and measurement setups
• Signal level reduction in transmitter chains
• Antenna system testing environments
• Broadband communication infrastructure

Attenuators Procurement Notes

Verify the specific datasheet provided by AO YUET (HK)ELECTRONICS LIMITED or the manufacturer for complete technical specifications. Confirm that the 7/16 female-to-female interface matches your system requirements. Ensure the 300 Watt power rating aligns with your operational peak power levels. Check for any regional distribution restrictions before placing orders.

Attenuators Selection Notes

Select this model when a fixed 10 dB attenuation is required in high-power scenarios up to 3 GHz. The dual female 7/16 connectors are suitable for connecting two male-ended cables or components. Consider the heatsink body design if ambient cooling is limited. Compare VSWR performance against other models if strict signal reflection limits are necessary for your application.

Attenuators Part Context

This component belongs to the Fairview Microwave series of connectorized attenuators. It is part of a family of high-power devices designed for robust RF environments. The 7/16 connector type offers superior power handling compared to smaller coaxial interfaces. This specific model fills the need for precise attenuation in bidirectional or directional high-power paths.

Attenuators Replacement Considerations

Direct substitutes include the SA3DMM300W-10, which shares identical electrical specifications but utilizes a male-to-male connector interface instead of female-to-female. Ensure mechanical compatibility with existing cabling when swapping between these variants.
