SA3-02

Attenuators Overview

The SA3-02 is a fixed attenuator manufactured by Fairview Microwave, designed for signal conditioning in radio frequency systems. It features SMA connectors with a male plug on one end and a female jack on the other. The device provides a nominal attenuation of 3 dB and operates within a frequency range from DC to 18 GHz. Constructed with a passivated stainless steel body, it ensures durability and consistent performance. The unit is rated for a maximum power handling capacity of 2 watts and maintains a voltage standing wave ratio (VSWR) of 1.35:1. It supports operating temperatures ranging from -65°C to +125°C, making it suitable for demanding environments.

Attenuators Feature Summary

• Provides precise 3 dB signal attenuation for RF applications
• Features robust passivated stainless steel construction
• Operates reliably across a wide temperature spectrum

Attenuators Applications

• RF signal level adjustment in test and measurement equipment
• Interconnecting components in microwave communication systems
• Impedance stabilization in high-frequency circuit designs

Attenuators Procurement Notes

Verify that the specific part number SA3-02 matches the required 3 dB attenuation value, as similar models may offer different attenuation levels. Confirm compatibility with SMA connector interfaces and ensure the 2-watt power rating meets system requirements. Check for RoHS compliance documentation if environmental regulations apply. Validate that the 18 GHz frequency range covers all operational bands. Review datasheet specifications for thermal management needs given the extended temperature range.

Attenuators Selection Notes

Select this component when a fixed 3 dB reduction in signal strength is required between SMA-connected devices. Consider the 18 GHz bandwidth for high-frequency applications requiring stable attenuation. The stainless steel body offers mechanical resilience compared to plated alternatives. Ensure the 2-watt power limit aligns with peak signal levels to prevent damage. Evaluate the VSWR specification for minimal reflection in sensitive transmission lines.

Attenuators Part Context

This attenuator belongs to Fairview Microwave's line of connectorized attenuators, specifically designed for integration into RF assemblies. It complements their range of cable assemblies and signal conditioning products. The SMA interface ensures broad compatibility with standard laboratory and industrial RF infrastructure. As a fixed attenuator, it serves as a passive component for controlling signal amplitude without active power sources.

Attenuators Replacement Considerations

Direct substitutes include other 3 dB SMA fixed attenuators from manufacturers such as Mini-Circuits or Pasternack. Verify identical connector gender, impedance matching, and power ratings before substitution. Cross-reference frequency response curves to ensure equivalent performance up to 18 GHz.
