M3933/16-05N

Overview

The M3933/16-05N is a military specification SMA attenuator manufactured by Amphenol SV Microwave. It features a female-to-male configuration and operates within a frequency range of DC to 18 GHz. The component provides a nominal attenuation of 1 dB with a 50 Ohm impedance. It supports a power rating of 2 Watts and functions across a temperature range of -65°C to +165°C. The unit is packaged in bulk.

Feature Summary

• Provides precise 1 dB signal attenuation for RF circuits
• Compatible with SMA connector interfaces up to 18 GHz
• Designed for high-temperature military environments

Applications

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

Procurement Notes

Verify the specific suffix 'N' indicates non-screened construction, distinct from screened variants. Confirm the female-to-male orientation matches the schematic requirements. Ensure the 1 dB attenuation value aligns with the design budget. Check for updated datasheets regarding environmental testing standards.

Selection Notes

Select this model when a low-loss, fixed 1 dB reduction is required at frequencies up to 18 GHz. The wide operating temperature range suits harsh environments. Consider the SMA interface compatibility with existing board layouts. Verify that the 2W power handling meets the system's peak power demands without overheating.

Part Context

This part belongs to the M3933 series of space attenuators designed for satellite applications. It complements other models like the M3933/16-05S, which offers screened construction. The series provides various attenuation values and configurations for precise RF power control in defense and aerospace systems.

Replacement Considerations

The M3933/16-05S is a screened alternative within the same series. Other M3933 models offer different attenuation levels or gender configurations. Verify mechanical fit and electrical performance before substituting with generic SMA attenuators.
