SA3-01

Attenuators Overview

The SA3-01 is a fixed attenuator manufactured by Fairview Microwave, designed for radio frequency applications up to 3 GHz. It features N-type connectors with a male plug on one side and a female jack on the other. The component provides a nominal attenuation of 1 dB at a system impedance of 50 Ohms. It supports an average power rating of 200 Watts at 25°C, derating linearly to 20 Watts at 125°C, with a peak power capacity of 10 kW. The Voltage Standing Wave Ratio (VSWR) is specified as a maximum of 1.35 at 3 GHz.

Attenuators Feature Summary

• Provides precise 1 dB signal attenuation within a 50 Ohm RF environment
• Supports high average power handling up to 200 Watts at ambient temperature
• Features robust N-type male-to-female connector interface for secure interconnection

Attenuators Applications

• RF signal level adjustment in test and measurement setups
• Power reduction for sensitive receiver inputs in communication systems
• Impedance matching and signal conditioning in microwave circuits

Attenuators Procurement Notes

Verify that the specific procurement request aligns with the high-power specifications of this model, particularly the 200W average rating. Confirm that the N-type connector gender configuration matches the system requirements. Ensure thermal management considerations are addressed if operating near the upper temperature limits where power derating applies. Cross-reference the datasheet for exact VSWR performance curves at target frequencies.

Attenuators Selection Notes

Select the SA3-01 when a low attenuation value of 1 dB is required alongside high power handling capabilities. This model is suitable for applications where standard attenuators may be insufficient due to power constraints. Consider the N-type interface compatibility with existing cabling infrastructure. Evaluate the need for the specific 1.35 VSWR limit against system return loss requirements.

Attenuators Part Context

This component belongs to the Fairview Microwave fixed attenuator series, which offers various attenuation values and connector types. The SA3-01 specifically addresses the need for minimal signal loss while maintaining high power integrity. It serves as a passive interconnect device within broader RF subsystems, ensuring signal fidelity across the 0 to 3 GHz frequency range.
