SA18E-16

Attenuators Overview

The SA18E-16 is a fixed attenuator manufactured by Fairview Microwave, designed for RF signal management. It provides a nominal attenuation of 16 dB with a frequency range extending from DC to 18 GHz. The component features SMA male (plug) to SMA female (jack) connectors and maintains a 50 Ohm impedance. Rated for 2 Watts of power handling, it utilizes a passivated stainless steel body and exhibits a VSWR of 1.35:1. Operational temperatures span from -65°C to +125°C.

Attenuators Feature Summary

• Provides precise 16 dB signal attenuation across a wide bandwidth up to 18 GHz
• Constructed with a durable passivated stainless steel body for environmental resilience
• Ensures low signal reflection through a stable 1.35:1 VSWR specification

Attenuators Applications

• RF test and measurement instrumentation setups
• Signal conditioning in wireless communication systems
• Laboratory circuit prototyping and validation

Attenuators Procurement Notes

Verify the specific datasheet version for the SA18E-16 model prior to ordering, as manufacturer specifications may undergo revisions. Confirm that the SMA connector gender configuration matches the system requirements exactly. Ensure the operating environment remains within the specified temperature limits of -65°C to +125°C to maintain performance integrity and prevent thermal damage during continuous operation.

Attenuators Selection Notes

Select this component when a 16 dB reduction is required at frequencies up to 18 GHz. The 2 Watt power rating suits moderate signal levels, while the SMA interface ensures compatibility with standard RF infrastructure. Consider the stainless steel construction for applications requiring robust mechanical stability and corrosion resistance in demanding environments.

Attenuators Part Context

This part belongs to the SA18E series of connectorized attenuators from Fairview Microwave. The series offers various attenuation values while maintaining consistent electrical performance and physical dimensions. All models share the same SMA connector type, 50 Ohm impedance, and general form factor, differing primarily in their specific dB ratings and internal resistive networks.

Attenuators Replacement Considerations

Compatible substitutes include other 16 dB fixed attenuators with SMA connectors rated for 18 GHz, such as those from Pasternack or Mini-Circuits. Verify that replacement parts match the 2 Watt power handling and 1.35:1 VSWR specifications to ensure equivalent system performance without modification.
