SA18N507-03

Attenuators Overview

The SA18N507-03 is a fixed directional attenuator manufactured by Fairview Microwave, designed for RF and microwave applications up to 18 GHz. It features N male plug to N female jack connectors with a nominal attenuation of 3 dB. The unit operates at a 50 Ohm impedance and supports a power rating of 50 Watts. Key electrical specifications include a Voltage Standing Wave Ratio (VSWR) of 1.55. The component utilizes a heatsink body construction to manage thermal loads effectively within its operational frequency range.

Attenuators Feature Summary

• Directional signal attenuation capability
• Heatsink body construction for thermal management
• N-type connector interface compatibility

Attenuators Applications

• RF test and measurement setups
• Microwave communication systems
• Signal level reduction in high-power circuits

Attenuators Procurement Notes

Verify the specific datasheet for the SA18N507-03 to confirm current manufacturing status and detailed mechanical drawings. Ensure that the 50 Watt power rating aligns with your system's thermal dissipation requirements. Confirm connector gender and orientation match your existing cabling infrastructure before integration.

Attenuators Selection Notes

Select this model when a 3 dB fixed attenuation is required at N-type interfaces up to 18 GHz. The 50 Watt rating distinguishes it from lower-power variants like the SA18NMNF25W series. Consider the 1.55 VSWR specification for applications requiring moderate signal reflection control. The heatsink design makes it suitable for continuous wave operations where thermal stability is critical.

Attenuators Part Context

This component belongs to the Fairview Microwave SA18 series of connectorized attenuators. It shares the same 18 GHz frequency limit and N-type connector style as other models in the family but differs in attenuation value and power handling compared to variants such as the SA18NMNF25W-03 or SA18NMNF50W-06.

Attenuators Replacement Considerations

The SA18NMNF50W-03 is a comparable alternative offering similar 50 Watt power handling and N-type connectors, though it specifies a 1.6 VSWR compared to the 1.55 VSWR of the SA18N507-03.
