SA4F75A-02

Attenuators Overview

The SA4F75A-02 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications requiring precise signal reduction. It features a 75 Ohm impedance and operates from DC to 3 GHz. The device connects via an F Male (Plug) to an F Female (Jack) interface. It provides a nominal attenuation of 2 dB with a maximum power rating of 0.25 Watts. The unit maintains a VSWR of 1.3:1 and includes a brass body with tri-metal plating.

Attenuators Feature Summary

• Provides stable 2 dB signal attenuation across the specified frequency range
• Utilizes standard F-type connectors for straightforward integration
• Constructed with durable brass housing and protective surface treatments

Attenuators Applications

• RF signal conditioning in broadcast systems
• Impedance matching in 75 Ohm transmission lines
• Signal level adjustment in video distribution networks

Attenuators Procurement Notes

Verify the specific connector gender configuration, as product descriptions may vary between plug-to-jack and jack-to-jack variants. Confirm that the 0.25 Watt power rating aligns with your system's thermal requirements. Ensure the 75 Ohm impedance matches your existing infrastructure to prevent signal reflection issues during installation.

Attenuators Selection Notes

Select this component when a low-power, 75 Ohm fixed attenuation solution is required up to 3 GHz. It is suitable for applications where minimal insertion loss variation is critical. Consider the physical size and mounting style if space constraints exist within the equipment chassis or cable assembly.

Attenuators Part Context

This part belongs to Fairview Microwave's line of connectorized attenuators. These components are engineered to provide consistent performance in RF environments. The series typically offers various attenuation values and impedance options to support diverse system architectures.

Attenuators Replacement Considerations

Direct substitutes must match the 75 Ohm impedance, F-type connectors, and 2 dB attenuation value. Verify that any alternative component supports the same 0.25 Watt power rating and 3 GHz frequency limit to ensure functional compatibility.
