M3933/14-21N

Overview

The M3933/14-21N is an RF attenuator manufactured by Amphenol SV Microwave, designed for military specification applications. It features SMA connectors with a male-to-female configuration and operates within a frequency range of DC to 12.4 GHz. The component provides a nominal attenuation value of 12 dB at a characteristic impedance of 50 Ohms. It supports a maximum power rating of 2 Watts and functions reliably across a temperature range from -65°C to +165°C. The unit is packaged in bulk.

Feature Summary

• Provides precise signal attenuation for RF circuits
• Compatible with standard SMA connector interfaces
• Designed for high-temperature military environments

Applications

• Satellite microwave circuit power level adjustment
• RF test and measurement equipment
• Military communication systems

Procurement Notes

Verify the specific datasheet version (e.g., document 10877) to confirm exact electrical tolerances and mechanical dimensions. Ensure compatibility with existing SMA mating hardware. Check for RoHS3 compliance status if required by project specifications. Confirm availability through authorized distributors as lead times may vary.

Selection Notes

Select this model when a fixed 12 dB attenuation is required for frequencies up to 12.4 GHz. Consider the 2W power handling capability against system requirements. Evaluate the SMA interface type against existing cabling infrastructure. Verify that the operating temperature range meets environmental conditions.
