M3933/16-16N

Overview

The M3933/16-16N is a coaxial attenuator manufactured by Amphenol SV Microwave, designed for high-frequency applications up to 18 GHz. It features SMA connectors with a male plug on one side and a female jack on the other, maintaining a standard 50 Ohm impedance. The device provides a fixed attenuation of 0 dB, effectively functioning as a pass-through interconnect while adhering to MIL-Spec standards. It operates within a temperature range of -65°C to +165°C and supports a power rating of 2 W. Packaged in bulk, this component ensures reliable signal transmission in demanding RF environments.

Feature Summary

• Provides zero-decibel attenuation for signal integrity maintenance
• Supports frequencies up to 18 GHz with SMA interface
• Operates reliably in extreme temperatures from -65°C to +165°C

Applications

• RF test and measurement setups requiring precise signal routing
• Military and aerospace communication systems
• High-frequency circuit board interconnections

Procurement Notes

Verify the specific attenuation value and connector gender configuration against the official datasheet before procurement, as variations exist within the M3933 series. Confirm that the 0 dB specification aligns with your system's requirement for a passive interconnect rather than an active attenuating component. Ensure compatibility with existing SMA infrastructure regarding impedance matching and physical dimensions.

Selection Notes

Select this model when a robust, MIL-Spec compliant interconnect is needed without signal loss. It is suitable for systems requiring operation at elevated temperatures up to 165°C. Consider the bulk packaging format for integration into custom assemblies or test fixtures where individual unit handling is preferred over tape-and-reel formats.

Part Context

This component belongs to the M3933 family of RF attenuators produced by Amphenol SV Microwave. While many parts in this series offer fixed attenuation values such as 0.5 dB or higher, the M3933/16-16N specifically serves as a 0 dB variant. It shares the same rugged construction and frequency capabilities as its attenuating counterparts but functions primarily as a high-performance connectorized cable segment.

Replacement Considerations

Direct substitutes include other 0 dB SMA attenuators from the same manufacturer, such as the M3933/16-17S (noted as 0.5 dB in some listings but functionally similar in form factor) or generic MIL-spec SMA pass-through adapters. Verify exact attenuation specifications, as some cross-reference models may introduce slight insertion loss.
