M3933/30-18N

Overview

The M3933/30-18N is a military specification RF attenuator manufactured by Amphenol SV Microwave. It belongs to the 2.92mm connector series and features SMA single-row module packaging. The component operates within a frequency range of 0 Hz to 32 GHz, with a maximum operational frequency of 40 GHz. It maintains a characteristic impedance of 50 Ohms and provides an attenuation value of 8.5 dB. The unit supports a power rating of 2W and functions reliably within a temperature range of -65°C to +165°C.

Feature Summary

• Provides precise signal attenuation for high-frequency RF applications
• Constructed with durable materials suitable for extreme environmental conditions
• Features robust SMA single-row module design for secure connectivity

Applications

• Military radar systems requiring stable signal levels

Procurement Notes

Verify the specific suffix designation against official Amphenol SV Microwave documentation to ensure correct gender configuration and screening level. Confirm that the required attenuation tolerance and power handling capabilities align with the system design specifications before finalizing procurement orders.

Selection Notes

Select this component when a fixed 8.5 dB attenuation is required in a 2.92mm interface environment. Ensure the application demands operation up to 32 GHz or 40 GHz and can accommodate the 2W power rating. Consider the wide operating temperature range if the deployment environment involves significant thermal variations.

Part Context

This part is part of the M3933 family of RF connectors and attenuators designed for military and aerospace standards. It utilizes the 2.92mm connector interface, which offers performance comparable to 3.5mm connectors but at higher frequencies. The series is engineered for reliability in harsh environments typical of defense and aviation sectors.
