SA18N5WA-30

Attenuators Overview

The SA18N5WA-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 Male (Plug) to Female (Jack). It is rated for 5 Watts of power handling and maintains a Voltage Standing Wave Ratio (VSWR) of 1.35:1. The unit utilizes a heatsink body construction.

Attenuators Feature Summary

• Fixed attenuation value of 30 dB
• Operates within a frequency range from DC to 18 GHz
• Utilizes N-type male plug to female jack interface
• Constructed with a heatsink body for thermal management

Attenuators Applications

• RF signal level reduction in test and measurement setups
• Protection of sensitive receiver inputs in communication systems
• Impedance matching and signal conditioning in high-frequency circuits

Attenuators Procurement Notes

Verify the specific connector gender configuration against system requirements, as variations exist within the product family. Confirm that the 5-watt power rating aligns with peak signal levels in the intended application. Ensure compatibility with standard N-type mating hardware. Review the official datasheet for precise mechanical dimensions and mounting constraints before integration.

Attenuators Selection Notes

Select this component when a 30 dB fixed attenuation is required at frequencies up to 18 GHz. The N-type interface suits applications requiring robust mechanical connections. The 5-watt power rating distinguishes it from higher-power variants like the SA18NFNF50W-30 or lower-power SMA versions. Consider the heatsink design for thermal dissipation needs in continuous wave operations.

Attenuators Part Context

This part belongs to the Fairview Microwave series of connectorized attenuators. It shares the 18 GHz frequency capability and 30 dB attenuation value with other models such as the SA18NFNF50W-30 and SA18S10W-30. Key differentiators include the N-type connector interface and the 5-watt power rating, which is lower than the 50-watt variant but higher than standard low-power SMA alternatives.

Attenuators Replacement Considerations

Publicly confirmed parametric equivalents include FMAT7461-30 and FMAT7624-30 from Fairview Microwave. Other potential substitutes listed in distributor databases are SA18N5WA-30 itself, SA6N5WA-30, and Rosenberger 53AS105-K30N3. Verify connector type and power ratings when substituting.
