M3933/14-21N

Overview

The M3933/14-21N is a coaxial RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It features SMA connectors and operates within a frequency range of 0 Hz to 12.4 GHz. The component provides an attenuation value of 12 dB at a system impedance of 50 Ohms. It has a power rating of 2 W and complies with the MIL-DTL-M3933 military specification.

Feature Summary

• Complies with MIL-DTL-M3933 military specifications for qualified parts list (QPL) components
• Utilizes SMA single-row module construction for reliable interconnection
• Designed for stable performance across a wide DC to 12.4 GHz frequency spectrum

Applications

• Military radio systems requiring precise signal level control
• Test and measurement instrumentation interfaces
• Avionics signal processing chains

Procurement Notes

Verify that the specific order includes the required qualification suffixes and packaging details mandated by the MIL-DTL-M3933 standard. Confirm that the manufacturer documentation explicitly supports the intended operational environment and connector gender requirements before finalizing procurement.

Selection Notes

Select this model when a fixed 12 dB attenuation is required within the 12.4 GHz bandwidth. Ensure the 2 W power handling capacity aligns with the system's maximum signal levels. Verify compatibility with existing SMA infrastructure and confirm compliance with specific military quality standards.

Part Context

This component belongs to the M3933/14 series of connectorized attenuators. It shares the same form factor and interface technology as other models in the family, differing primarily in its specific attenuation value and frequency characteristics defined by the MIL-DTL-M3933 standard.

Replacement Considerations

M3933/14-21S serves as a functional equivalent within the same series, offering identical electrical parameters but potentially differing in connector gender or screening requirements.
