SA18N200WA-20

Attenuators Overview

The SA18N200WA-20 is a fixed attenuator manufactured by Fairview Microwave, designed for high-power RF applications. It provides a nominal attenuation of 20 dB with a maximum operating frequency of 18 GHz and a power rating of 200 W. The device utilizes N-type connectors, featuring a male plug on one end and a female jack on the other. It maintains a 50 Ohm impedance and exhibits a Voltage Standing Wave Ratio (VSWR) of 1.6. The unit incorporates a heatsink body to manage thermal loads effectively.

Attenuators Feature Summary

• Supports high continuous power handling up to 200 Watts
• Operates across a wide frequency range from DC to 18 GHz
• Features an integrated heatsink body for efficient thermal dissipation

Attenuators Applications

• High-power signal testing and measurement systems
• RF amplifier output stage protection
• Base station transmitter line conditioning

Attenuators Procurement Notes

Verify the specific connector gender configuration and directional capabilities against project requirements before ordering. Confirm that the 200W power rating aligns with peak and average signal levels in the intended circuit. Ensure the N-type interface matches existing cabling infrastructure. Check for any specific environmental ratings or mounting hardware requirements associated with the heatsink design.

Attenuators Selection Notes

Select this component when high power dissipation is critical alongside broadband performance up to 18 GHz. The 200W rating distinguishes it from lower-power variants like the SA18NMNF25W-20. Consider the physical dimensions and thermal management needs due to the substantial heatsink body. Ensure the 20 dB attenuation value fits the system loss budget without excessive signal degradation.

Attenuators Part Context

This model belongs to Fairview Microwave's series of connectorized attenuators. It shares the N-type interface and 18 GHz frequency limit with other models but differs significantly in power handling capacity. Unlike lower-rated units, it is engineered for robust thermal management suitable for demanding RF environments.

Attenuators Replacement Considerations

SA18N200WA-40 offers higher attenuation. Lower power alternatives include SA18NMNF25W-20. Verify compatibility if substituting with non-directional variants.
