SA18L-60

Attenuators Overview

The SA18L-60 is a fixed attenuator manufactured by Fairview Microwave, designed for radio frequency applications up to 18 GHz. It features SMA connectors with a male plug on one end and a female jack on the other. The unit provides a maximum attenuation of 60 dB at a system impedance of 50 Ohms. It is rated for a power handling capacity of 2 Watts and maintains a Voltage Standing Wave Ratio (VSWR) of 1.35:1. The device operates within a temperature range of -54°C to +125°C and utilizes a passivated stainless steel body.

Attenuators Feature Summary

• Provides precise signal reduction with 60 dB fixed attenuation across a wide bandwidth.
• Constructed with a durable passivated stainless steel body for environmental resistance.
• Ensures signal integrity through a low VSWR of 1.35:1 over the operational frequency range.

Attenuators Applications

• RF signal path attenuation in communication systems
• Test and measurement equipment calibration
• Protecting sensitive receiver inputs from high power levels

Attenuators Procurement Notes

Verify the specific connector gender configuration matches the design requirements, as this model specifies a male-to-female interface. Confirm that the 2 Watt power rating is sufficient for the intended application environment. Ensure the operating temperature range aligns with the deployment conditions. Cross-reference the datasheet for detailed mechanical dimensions and mounting specifications before integration.

Attenuators Selection Notes

Select this component when high attenuation values are required in a compact form factor. The SMA interface suits board-level or cable assembly integration where space is limited. Consider the 2 Watt power limit carefully; higher power applications may require heatsink-equipped models. Verify compatibility with existing SMA infrastructure to ensure proper mating without adapters.

Attenuators Part Context

This part belongs to the Fairview Microwave SA18 series of fixed attenuators, which operate up to 18 GHz. The series includes various attenuation values and connector configurations. This specific model uses SMA connectors, distinguishing it from N-type or TNC variants in the same frequency range. The passivated stainless steel construction is common across the lower-power SMA models in this lineup.

Attenuators Replacement Considerations

Direct substitutes include other SA18L-series parts with different attenuation values, such as SA18L-50 or SA18L-40, provided the attenuation requirement changes. For identical specifications, verify availability from authorized distributors. Ensure any replacement maintains the SMA male-to-female configuration and 50 Ohm impedance.
