SA4S25-02

Attenuators Overview

The SA4S25-02 is a fixed RF attenuator manufactured by Fairview Microwave. It provides an attenuation value of 2 dB across a frequency range from 0 Hz to 4 GHz. The component features SMA male plug to SMA female jack connectors and maintains a VSWR of 1.2. It is rated for 25 watts of power handling and utilizes a heatsink body construction.

Attenuators Feature Summary

• Provides precise 2 dB signal attenuation
• Operates effectively up to 4 GHz frequency
• Constructed with a heatsink body for thermal management

Attenuators Applications

• RF signal level adjustment in test equipment
• Attenuation stages in microwave measurement systems
• Signal conditioning in wireless communication infrastructure

Attenuators Procurement Notes

Verify the specific connector gender configuration matches the system requirements, as SMA variants exist. Confirm the power rating aligns with peak signal levels in the application. Check RoHS compliance status if environmental regulations apply. Ensure the operating frequency range covers the intended signal bandwidth without performance degradation.

Attenuators Selection Notes

Select this model when a low insertion loss of 2 dB is required within the sub-4 GHz spectrum. The heatsink design supports high-power applications up to 25 watts. Compare against other attenuation values if signal reduction needs differ. Ensure SMA interface compatibility with existing cabling and fixtures.

Attenuators Part Context

This component belongs to the Fairview Microwave series of connectorized attenuators. These devices are designed for reliable performance in RF and microwave environments. The product line emphasizes durability and consistent electrical characteristics across various frequency bands.

Attenuators Replacement Considerations

Direct substitutes include models with identical 2 dB attenuation and SMA interfaces. Verify that replacement units maintain the 25-watt power rating and 4 GHz frequency limit. Ensure physical dimensions allow for installation in existing heatsink mounts.
