SA18T25W-10

Attenuators Overview

The SA18T25W-10 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It features a TNC male (plug) to TNC female (jack) configuration with a 50 Ohm impedance. The unit provides a nominal attenuation of 10 dB and is rated for continuous power handling of 25 Watts. It incorporates a heatsink body to manage thermal dissipation effectively. The Voltage Standing Wave Ratio (VSWR) is specified at 1.6, ensuring signal integrity across the frequency range.

Attenuators Feature Summary

• Features a robust heatsink body construction for enhanced thermal management during high-power operation.
• Provides stable 10 dB attenuation within a wide frequency range extending up to 18 GHz.
• Utilizes durable TNC connectors to ensure reliable male-to-female interconnection in RF systems.

Attenuators Applications

• RF signal level reduction in test and measurement setups
• Impedance matching in microwave communication circuits
• Protection of sensitive receiver inputs from high power signals

Attenuators Procurement Notes

Verify the specific datasheet version for precise VSWR and power rating tolerances before integration. Confirm that the TNC connector gender matches the system interface requirements. Ensure the operating environment allows for adequate heat dissipation due to the heatsink design. Cross-reference the part number with official Fairview Microwave documentation to confirm current manufacturing status.

Attenuators Selection Notes

Select this component when a 10 dB attenuation value is required for frequencies up to 18 GHz. The TNC interface is suitable for applications requiring secure screw-lock connections. The 25 Watt power rating makes it appropriate for medium-power RF environments. Consider the physical dimensions and heatsink profile for enclosure compatibility.
