M3933/30-35N

Overview

The M3933/30-35N is a fixed RF attenuator manufactured by Amphenol SV Microwave, designed for high-frequency applications up to 32 GHz. It features a 2.92mm interface with female-to-male connector configuration and maintains a 50 Ohm impedance. The component provides a nominal attenuation value of 30 dB and supports a power rating of 2 Watts. Operating within a temperature range of -65°C to +165°C, it is classified as a non-screened MIL-spec device suitable for demanding environments.

Feature Summary

• Provides precise signal attenuation in the 2.92mm frequency band
• Supports extreme operating temperatures for rugged deployment
• Features robust SMA-style inline module construction

Applications

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

Procurement Notes

Verify the specific datasheet version and manufacturing lot details upon order confirmation. Ensure that the receiving facility has appropriate handling procedures for sensitive RF components. Confirm that the non-screened designation aligns with the electromagnetic interference requirements of the final assembly. Cross-reference the part number suffix to confirm the exact gender configuration and attenuation tolerance before integration.

Selection Notes

Select this model when a 30 dB attenuation value is required within the 2.92mm frequency range. Consider the 2 Watt power handling capability against the system's maximum signal levels. Evaluate the need for non-screened construction versus screened alternatives based on shielding requirements. Verify compatibility with existing 50 Ohm infrastructure and ensure the male-to-female interface matches the system cabling.

Part Context

This component belongs to the M3933 series of space attenuators from Amphenol SV Microwave. These devices are engineered for satellite microwave circuits and offer DC to 40 GHz performance. The series includes various attenuation values and connector configurations, providing standardized solutions for military and aerospace RF applications requiring reliable signal control.

Replacement Considerations

M3933/30-35S is a screened equivalent variant within the same series. Verify if shielding requirements necessitate switching to the screened version. Other models in the M3933/30 series offer different attenuation values but share similar electrical characteristics.
