SA18TMTF25W-20

Attenuators Overview

The SA18TMTF25W-20 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It features TNC connectors with a male plug on one end and a female jack on the other. The unit provides a nominal attenuation of 20 dB at a system impedance of 50 Ohms. It is rated for a maximum power handling capacity of 25 Watts. The device incorporates a heatsink body to manage thermal dissipation during operation.

Attenuators Feature Summary

• Incorporates a heatsink body for effective thermal management
• Provides fixed 20 dB signal attenuation
• Supports frequency range from DC to 18 GHz

Attenuators Applications

• RF signal level reduction in test setups
• Protection of sensitive receiver inputs
• Impedance matching in microwave circuits

Attenuators Procurement Notes

Verify the specific connector gender configuration matches the design requirements, as this model utilizes a male-to-female interface. Confirm that the 25 Watt power rating aligns with the peak power levels present in the application circuit. Ensure the operating frequency does not exceed the 18 GHz upper limit specified for the component.

Attenuators Selection Notes

Select this component when a fixed 20 dB attenuation value is required within an 18 GHz bandwidth. The 25 Watt power rating makes it suitable for moderate power applications where heat dissipation is a concern. The TNC interface should be chosen if compatibility with existing TNC cabling or equipment is necessary for the installation.

Attenuators Part Context

This part belongs to the Fairview Microwave series of connectorized attenuators. These components are engineered to provide precise signal control in radio frequency systems. The product line typically includes various attenuation values and connector types to support diverse engineering needs across different frequency bands.

Attenuators Replacement Considerations

SA18TFTF25W-20 offers identical electrical specifications but uses a female-to-female connector interface instead of male-to-female.
