SA18N50W-03

Attenuators Overview

The SA18N50W-03 is a fixed attenuator manufactured by Fairview Microwave, designed for high-frequency applications up to 18 GHz. It features N-type female connectors on both ends and provides a nominal attenuation of 3 dB. The device is rated for a power handling capacity of 50 Watts and maintains a Voltage Standing Wave Ratio (VSWR) of 1.6. Constructed with a heatsink body, it ensures thermal stability during operation. The unit operates within a temperature range of -55°C to +125°C and has a characteristic impedance of 50 Ohms.

Attenuators Feature Summary

• Features N-type female-to-female connector configuration for seamless integration into RF systems.
• Incorporates a heatsink body design to manage thermal dissipation effectively at high power levels.
• Supports frequency ranges from DC to 18 GHz with stable 3 dB attenuation performance.

Attenuators Applications

• RF signal path conditioning in microwave communication systems
• Test and measurement setups requiring precise signal level reduction
• High-power amplifier output stage protection

Attenuators Procurement Notes

Verify the specific datasheet version and physical dimensions prior to procurement, as specifications are subject to change without notice. Confirm that the 50-watt power rating aligns with your system's peak power requirements. Ensure connector compatibility with existing N-type female interfaces. Check for any recent updates to the VSWR or thermal characteristics in the official manufacturer documentation before finalizing orders.

Attenuators Selection Notes

Select this component when a 3 dB attenuation value is required for N-type interconnects in high-power environments. The 50-watt rating distinguishes it from lower-power variants like the SA18NFNF25W-03. Consider the heatsink body for applications where thermal management is critical. Verify that the 1.6 VSWR meets the system's return loss requirements. This model is suitable for frequencies up to 18 GHz, making it appropriate for broad-band microwave applications.

Attenuators Part Context

This part belongs to the SA18 series of connectorized attenuators from Fairview Microwave. It shares the same frequency range and connector type with other models but differs in power rating and attenuation value. For instance, the SA18NFNF25W-03 offers similar electrical performance but with a lower 25-watt power rating. The SA18N50W-03 is positioned as a higher-power solution within the N-type fixed attenuator lineup.
