M3933/25-83N

Overview

The M3933/25-83N is a radio frequency military specification connector manufactured by Amphenol SV Microwave. It belongs to the SMA series and features a male-to-female attenuator configuration. The component operates within a frequency range of DC to 18 GHz with a characteristic impedance of 50 Ohms. It provides a maximum attenuation of 10 dB. The unit is designed for non-screened applications and functions reliably across an operating temperature range from -65°C to +165°C.

Feature Summary

• SMA male-to-female attenuator design
• Operates up to 18 GHz frequency range
• Military specification construction
• Non-screened body type

Applications

• RF test and measurement equipment
• Military communication systems
• Aerospace signal conditioning
• High-frequency circuit attenuation

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm the 10 dB attenuation value and SMA interface compatibility. Ensure the non-screened variant matches the system requirements, as screened alternatives exist within the same series. Cross-reference the temperature ratings and power handling capabilities with the latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when a fixed 10 dB attenuation is required in an SMA environment. Consider the non-screened form factor for space-constrained or specific shielding architectures. Evaluate the 18 GHz operational limit against system bandwidth needs. Confirm that the military-grade specifications align with environmental durability requirements for the intended deployment scenario.

Part Context

This model is part of the M3933 series, which encompasses various RF attenuators designed for rugged applications. The series includes both screened and non-screened options across different attenuation values. It represents a standardized solution for integrating precise signal reduction into high-frequency military and aerospace interconnects without compromising structural integrity.

Replacement Considerations

M3933/25-78N offers identical SMA male-to-female configuration and 18 GHz frequency range but provides 10 dB attenuation. Verify mechanical dimensions and mounting requirements to ensure interchangeability. Check if screened variants are necessary for specific electromagnetic interference mitigation needs.
