SA18N50W-30

Attenuators Overview

The SA18N50W-30 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It provides a nominal attenuation of 30 dB with a 50 Ohm impedance. The device features N-type connectors, specifically a male plug to female jack configuration. It is rated for 50 Watts of power handling and exhibits a VSWR of 1.5. Constructed as an in-line module, it operates within a temperature range of -55°C to +125°C.

Attenuators Feature Summary

• Provides precise 30 dB signal attenuation across a wide frequency spectrum up to 18 GHz.
• Features robust N-type male-to-female connector interface for secure interconnection.
• Engineered with a heatsink body design to manage thermal loads at high power levels.

Attenuators Applications

• RF test and measurement setups requiring precise signal level reduction.
• High-power microwave communication systems needing signal attenuation.
• Laboratory equipment calibration and signal conditioning circuits.

Attenuators Procurement Notes

Verify the specific connector gender configuration (male plug to female jack) against system requirements before procurement. Confirm that the 50 Watt power rating and 1.5 VSWR specifications align with the operational limits of the target application. Ensure compatibility with standard N-type mating hardware to maintain optimal performance and signal integrity during installation.

Attenuators Selection Notes

Select this component when a 30 dB attenuation value is required within the 0 Hz to 18 GHz bandwidth. Choose this model over lower-rated variants if the application involves continuous power levels approaching 50 Watts. Consider the physical dimensions and weight constraints associated with the heatsink body design during mechanical integration planning.

Attenuators Part Context

This part belongs to the SA18 series of connectorized attenuators from Fairview Microwave. The series offers various attenuation values and power ratings tailored for different RF environments. The SA18N50W-30 specifically addresses needs for high-power, moderate-attenuation applications using standard N-type interfaces, distinguishing it from SMA or lower-power variants in the lineup.

Attenuators Replacement Considerations

Direct substitutes include models with identical electrical parameters such as SA18NFNM50W-30, though connector gender configurations may differ. Verify that any replacement maintains the 50 Watt power rating and 18 GHz frequency limit to ensure functional equivalence without compromising system safety or performance.
