M3933/16-04S

Overview

The M3933/16-04S is a fixed RF attenuator manufactured by Amphenol SV Microwave, designed for military and aerospace applications. It features SMA connectors with a male-to-female configuration and operates within a frequency range of DC to 18 GHz. The component provides a nominal attenuation value of 20 dB at 50 Ohms impedance. It supports a maximum power rating of 2 Watts and functions reliably across an operating temperature range from -65°C to +165°C.

Feature Summary

• Provides fixed signal attenuation in a ruggedized inline module format suitable for harsh environments.
• Utilizes standard SMA interface geometry for seamless integration into existing RF test and measurement setups.
• Engineered to meet stringent MIL-Spec reliability standards for defense and aviation systems.

Applications

• Military radar system signal conditioning
• Aerospace communication equipment testing
• RF power level reduction in satellite ground stations

Procurement Notes

Verify the specific suffix designation against official Amphenol documentation to confirm screening levels and connector gender orientation. Ensure environmental compliance requirements align with project specifications before finalizing procurement orders.

Selection Notes

Select this model when a precise 20 dB attenuation is required within the 18 GHz bandwidth. Confirm that the 2W power handling capacity meets circuit demands and that the SMA form factor matches the host system's interconnect requirements.

Part Context

This component belongs to the M3933 series of space-attenuators, which are characterized by their compact inline design and high-frequency performance. The series is widely utilized in scenarios requiring stable attenuation values without introducing significant phase shift or reflection.

Replacement Considerations

M3933/16-04N serves as a parameter-equivalent alternative within the same product family, offering identical electrical specifications but potentially differing in screening or packaging details.
