SA18N-20

Attenuators Overview

The SA18N-20 is a fixed attenuator manufactured by Fairview Microwave, designed for radio frequency applications. It provides a nominal attenuation of 20 dB across a frequency range from 0 Hz to 18 GHz. The component features N-type connectors with a male plug on one end and a female jack on the other. It operates within a 50 Ohm impedance system and is rated for 2 Watts of power handling capacity. The unit utilizes an in-line module package design.

Attenuators Feature Summary

• Provides fixed signal attenuation suitable for RF circuit protection and level adjustment
• Operates over a wide bandwidth extending from DC up to 18 GHz
• Features robust N-type connector interface for secure cable integration

Attenuators Applications

• RF signal path conditioning in communication systems
• Test and measurement equipment requiring precise signal reduction
• Wireless infrastructure components operating at high frequencies

Attenuators Procurement Notes

Verify the specific power rating configuration when sourcing this component, as distributor listings may reference varying wattage specifications such as 2W or higher ratings for similar model numbers. Confirm that the connector polarity matches the required male-to-female topology for the intended application before finalizing procurement orders.

Attenuators Selection Notes

Select this attenuator when a 20 dB reduction is required within an 18 GHz bandwidth using standard N-type interfaces. Ensure the system power levels remain within the specified thermal limits for the selected power rating variant. Consider the physical dimensions and mounting requirements associated with the in-line module form factor during system integration planning.

Attenuators Part Context

This component belongs to the Fairview Microwave fixed attenuator series, which offers various attenuation values and connector configurations. The SA18N-20 specifically addresses needs for moderate signal reduction in broadband RF environments. It complements other models in the lineup that offer different dB values or power handling capabilities for diverse engineering requirements.

Attenuators Replacement Considerations

Equivalent parts include SA18NMNF25W-20 for higher power handling or SA18NMNF50W-20 variants if available. Cross-reference with Amphenol or Mini-Circuits N-type attenuators ensuring identical 20 dB attenuation and 18 GHz upper frequency limit.
