M3933/16-22N

Overview

The M3933/16-22N is a military specification SMA attenuator manufactured by Amphenol SV Microwave. It features a female-to-male connector configuration and operates within a frequency range up to 18 GHz. The component provides a nominal attenuation of 5.5 dB at a characteristic impedance of 50 Ohms. It supports a power rating of 2 W and functions reliably across an operating temperature range from -65 °C to +165 °C. This screened inline module is designed for high-reliability RF applications requiring precise signal reduction.

Feature Summary

• Military-grade construction compliant with MIL-Spec standards
• Screened design for enhanced environmental protection
• Inline module format for direct circuit integration

Applications

• Defense communication systems
• Aviation radar equipment
• Test and measurement instrumentation

Procurement Notes

Verify the specific screening requirements against project specifications, as this model denotes screened construction. Confirm that the SMA female-to-male orientation matches the system interconnect needs. Ensure the 5.5 dB attenuation value aligns with the required signal loss parameters. Validate that the 2 W power handling capacity is sufficient for the operational environment. Check compatibility with the specified temperature extremes during final assembly planning.

Selection Notes

Select this component when a screened military-specification attenuator is required for frequencies up to 18 GHz. The 5.5 dB attenuation value suits applications needing moderate signal reduction. The wide temperature range makes it suitable for harsh environments. Consider the SMA interface compatibility with existing connectors. Evaluate the 2 W power rating against peak signal levels to prevent damage.

Part Context

This part belongs to the M3933 series of RF attenuators from Amphenol SV Microwave. The series offers various attenuation values and connector configurations under military specifications. The '16' in the model number typically indicates the screened variant within this product line. These components are engineered for durability and consistent performance in demanding RF applications.

Replacement Considerations

Direct substitutes include other screened SMA attenuators with identical 5.5 dB attenuation and 18 GHz bandwidth. Verify mechanical dimensions and pinout compatibility before substitution. Alternative models may offer different screening levels or power ratings.
