SA18E-02

Attenuators Overview

The SA18E-02 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 maximum attenuation of 2 dB with a 50 Ohm impedance. It is rated for 2 Watts of power handling and maintains a VSWR of 1.35:1. The body is constructed from passivated stainless steel, ensuring durability in demanding environments. The unit supports an operating temperature range from -65°C to +125°C.

Attenuators Feature Summary

• Provides precise signal attenuation using SMA male-to-female connector interface
• Constructed with passivated stainless steel housing for environmental resistance
• Maintains stable performance across a wide microwave frequency spectrum up to 18 GHz

Attenuators Applications

• RF test and measurement setups requiring low-level signal reduction
• Microwave circuit protection and impedance matching networks

Attenuators Procurement Notes

Verify the specific datasheet version for the SA18E-02 to confirm current manufacturing status and compliance details. Ensure that the SMA connector gender and orientation match the system requirements exactly. Check for any updates regarding material specifications or RoHS compliance documentation before finalizing procurement orders to avoid integration issues.

Attenuators Selection Notes

Select this model when a low attenuation value of 2 dB is required at frequencies extending to 18 GHz. The SMA interface makes it suitable for compact PCB or cable assemblies where standard coaxial connections are needed. Consider the 2W power rating and stainless steel construction if the application involves moderate power levels or requires corrosion resistance compared to plated brass alternatives.
