SA18E-30

Attenuators Overview

The SA18E-30 is a fixed RF attenuator manufactured by Fairview Microwave, designed for signal reduction in coaxial systems. It provides a nominal attenuation of 30 dB across a frequency range from DC to 18 GHz. The component features SMA connectors, with a male plug on one end and a female jack on the other. It has a 50 Ohm impedance and is rated for a maximum power handling of 2 Watts. The unit utilizes a passivated stainless steel body and maintains a Voltage Standing Wave Ratio (VSWR) of 1.35:1. Operating temperatures range from -65°C to +125°C.

Attenuators Procurement Notes

Verify that the specific order matches the SA18E-30 model number to ensure correct 30 dB attenuation and SMA connector configuration. Confirm that the required power rating of 2 Watts and frequency range up to 18 GHz align with the application needs. Check the operating temperature specifications against environmental conditions. Ensure compatibility with existing SMA male and female interfaces in the system design before finalizing procurement.

Attenuators Selection Notes

Select this component when a high attenuation value of 30 dB is required within an 18 GHz bandwidth. The SMA interface makes it suitable for standard coaxial connections. Consider the 2 Watt power limit and stainless steel construction for durability. This model is appropriate for applications needing significant signal reduction without compromising frequency response or mechanical stability in harsh environments.

Attenuators Part Context

The SA18E-30 belongs to the series of connectorized attenuators produced by Fairview Microwave. These components are engineered for precision in RF and microwave circuits. The series offers various attenuation values and connector types to suit different system requirements. This specific model focuses on high attenuation capabilities using robust materials for reliable performance in demanding electronic applications.

Attenuators Replacement Considerations

Direct substitutes must match the 30 dB attenuation, SMA male-to-female interface, and 18 GHz frequency range. Verify equivalent power ratings and VSWR specifications. Alternative models from the same manufacturer may offer different connector styles or attenuation levels but require careful comparison of electrical parameters to ensure functional interchangeability.
