M3933/30-10N

Overview

The M3933/30-10N is a 2.92mm in-line RF attenuator manufactured by Amphenol SV Microwave. It provides a nominal attenuation of 4.5 dB with a frequency range extending from DC to 32 GHz. The component features a 50 Ohm impedance and supports a maximum power rating of 2 Watts. Designed for rugged environments, it operates within a temperature range of -65°C to +165°C. This nonscreened unit utilizes SMA single-row module packaging.

Feature Summary

• Provides precise 4.5 dB signal attenuation across high-frequency bands up to 32 GHz
• Engineered for extreme thermal stability operating between -65°C and +165°C
• Supports continuous 2W RF power handling in compact in-line modules

Applications

• Satellite microwave circuit power level adjustment
• RF test and measurement instrumentation
• Military communication systems requiring stable attenuation

Procurement Notes

Verify the specific datasheet version (e.g., document 10887) against the ordered part number to confirm exact electrical tolerances and mechanical dimensions. Ensure the nonscreened configuration aligns with system shielding requirements. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this model when a fixed 4.5 dB loss is required at frequencies approaching 32 GHz. The 2.92mm interface ensures compatibility with high-frequency connectors while maintaining 50 Ohm impedance matching. Consider the nonscreened design for applications where external shielding is provided or unnecessary.

Part Context

This component belongs to the M3933 series of space attenuators designed for satellite and microwave circuits. It represents a specialized subset of RF interconnect solutions offering fixed attenuation values. The series targets high-reliability applications demanding consistent performance under harsh environmental conditions.

Replacement Considerations

M3933/30-10S serves as a parameter-equivalent screened alternative. Verify that the screening difference does not impact electromagnetic interference requirements in the target application.
