M3933/14-05N

Overview

The M3933/14-05N is an RF attenuator manufactured by Amphenol SV Microwave, designed for military specification applications. It features SMA male-to-female connectors and operates within a frequency range of DC to 12.4 GHz. The component provides a nominal attenuation value of 15 dB at a system impedance of 50 Ohms. It supports a maximum power rating of 2 W and functions reliably across an operating temperature range from -65 °C to +165 °C. The unit is classified as a nonscreened in-line module.

Feature Summary

• Provides precise signal attenuation for RF circuits using SMA interconnects
• Engineered for high-temperature stability suitable for harsh environments
• Designed as a nonscreened inline module for direct circuit integration

Applications

• Satellite microwave circuit power level adjustment
• Military RF system signal conditioning
• Test and measurement equipment calibration

Procurement Notes

Verify the specific datasheet version for the M3933/14-05N to confirm current manufacturing status and compliance with RoHS3 standards. Ensure that the nonscreened configuration aligns with your electromagnetic interference requirements. Cross-reference the SMA gender orientation and physical dimensions against your PCB or cable assembly design specifications before finalizing procurement orders.

Selection Notes

Select this component when a fixed 15 dB attenuation is required within the 12.4 GHz bandwidth. Consider the 2 W power handling capability relative to your system's peak signal levels. The wide temperature range makes it suitable for aerospace or defense applications where standard commercial components may fail. Verify that the nonscreened construction meets your shielding needs.

Part Context

This part belongs to the M3933 series of RF attenuators from Amphenol SV Microwave. These components are specifically engineered to meet rigorous military specifications for reliability and performance. The series offers various attenuation values and connector configurations to support diverse RF system architectures requiring stable signal reduction.

Replacement Considerations

M3933/14-05S is a parameter-equivalent screened variant. Verify if shielding requirements differ between the nonscreened M3933/14-05N and its screened counterpart.
