SA18N507-20

Attenuators Overview

The SA18N507-20 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It provides a nominal attenuation of 20 dB with a maximum frequency range extending from 0 Hz to 18 GHz. The component features N-type connectors, specifically a male plug on one end and a female jack on the other. It is rated for a power handling capacity of 50 Watts and maintains a Voltage Standing Wave Ratio (VSWR) of 1.55. The unit utilizes a heatsink body construction and operates within a temperature range of -65°C to +125°C.

Attenuators Feature Summary

• Directional design for controlled signal flow
• Heatsink body construction for thermal management
• Mixed gender connector configuration

Attenuators Applications

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

Attenuators Procurement Notes

Verify that the specific part number matches the directional requirement, as non-directional equivalents exist within the same family. Confirm connector gender alignment with system interfaces, noting the male-to-female configuration. Ensure environmental ratings meet operational temperature extremes if deployed in harsh conditions.

Attenuators Selection Notes

Select this model when a directional characteristic is required for precise signal monitoring or isolation. The 50-watt rating supports higher power levels compared to standard attenuators. Consider the mixed gender connectors if direct mating with standard N-type equipment is needed without adapters.

Attenuators Part Context

This component belongs to the Fairview Microwave series of connectorized attenuators. It is distinguished by its directional capability and robust heatsink design, differentiating it from non-directional variants like the SA18NFNF25W-20 which lacks directionality and uses female-to-female connections.

Attenuators Replacement Considerations

SA18NFNF20W-20: Non-directional alternative with female-to-female connectors. SA18N507-30: Same form factor but with 30 dB attenuation.
