SA18N-02

Attenuators Overview

The SA18N-02 is a fixed coaxial attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It provides a nominal attenuation of 2 dB with a maximum frequency range of DC to 18 GHz. The component features N-type connectors, specifically a male plug to female jack configuration. It operates at a characteristic impedance of 50 Ohms and supports a power rating of 2 Watts. The Voltage Standing Wave Ratio (VSWR) is specified as 1.5:1. The unit utilizes a passivated stainless steel body and functions within an operating temperature range of -65°C to +125°C.

Attenuators Feature Summary

• Fixed 2 dB attenuation performance across a wide frequency bandwidth up to 18 GHz
• Robust construction utilizing a passivated stainless steel body for durability
• Standardized N-type connector interface ensuring compatibility with common RF systems

Attenuators Applications

• RF signal level adjustment in test and measurement setups
• Power reduction in microwave communication circuits
• Impedance matching and signal conditioning in high-frequency electronic systems

Attenuators Procurement Notes

Verify the specific datasheet version for the SA18N-02 to confirm current manufacturing status and detailed electrical tolerances. Ensure that the required power handling capacity of 2 Watts aligns with system requirements before integration. Confirm connector gender and mating compatibility with existing N-type infrastructure to prevent interface mismatches during installation.

Attenuators Selection Notes

Select this model when a precise 2 dB reduction is required within the 0 to 18 GHz spectrum. The N-type interface makes it suitable for general-purpose RF environments where standard connectors are preferred. Consider the 2 Watt power limit and the specific VSWR value of 1.5:1 to ensure signal integrity and thermal management meet the application's operational constraints.

Attenuators Part Context

This component belongs to the SA18 series of fixed attenuators from Fairview Microwave, which covers frequencies up to 18 GHz. The series includes various attenuation values and connector types, such as SMA and N-type variants. The SA18N-02 specifically addresses the need for low-loss signal attenuation using robust N-type connections, distinguishing it from higher-power or different-connector models within the same product family.

Attenuators Replacement Considerations

Direct substitutes include other 2 dB fixed attenuators with N-type connectors and similar 18 GHz frequency limits. Verify that alternative parts match the 50 Ohm impedance, 2 Watt power rating, and comparable VSWR specifications to maintain system performance without modification.
