SA18S5W-03

Attenuators Overview

The SA18S5W-03 is a fixed attenuator manufactured by Fairview Microwave, designed for RF interconnect applications. It features SMA male (plug) to SMA female (jack) connectors and operates within a frequency range of 0 Hz to 18 GHz. The component provides a nominal attenuation of 3 dB with a characteristic impedance of 50 Ohms. It is rated for a continuous power handling capacity of 5 Watts and maintains a Voltage Standing Wave Ratio (VSWR) of 1.35. The unit weighs approximately 77.791 grams and is packaged individually in a bag.

Attenuators Feature Summary

• Provides precise 3 dB signal attenuation across a wide bandwidth from DC to 18 GHz
• Features SMA male-to-female inline connectivity for standard RF circuit integration
• Constructed with a heatsink body to manage thermal dissipation at rated power levels

Attenuators Applications

• RF signal level adjustment in test and measurement equipment
• Signal conditioning in wireless communication systems
• Attenuation insertion in high-frequency circuit boards

Attenuators Procurement Notes

Verify the specific datasheet version when ordering, as specifications are subject to change without notice. Confirm that the SMA connector gender configuration matches the system requirements. Ensure the 5 Watt power rating is sufficient for the intended application environment. Check for RoHS compliance details if required by project standards. Validate the operating temperature range against environmental conditions.

Attenuators Selection Notes

Select this model when a 3 dB fixed attenuation value is required up to 18 GHz. Choose the SMA interface for compatibility with existing SMA-based infrastructure. Consider the 5 Watt power limit for moderate power applications. Compare VSWR performance against other models if strict impedance matching is critical. Evaluate the heatsink design benefits over non-heatsink variants for thermal management.
