M3933/16-03N

Overview

The M3933/16-03N is an RF attenuator from Amphenol SV Microwave, designed for military specifications. 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 of 10 dB at a characteristic impedance of 50 Ohms. It supports a power rating of 2 W and functions reliably across a temperature range of -65°C to +165°C. This non-screened inline module is packaged in bulk.

Feature Summary

• Provides precise signal attenuation via SMA male-to-female inline connection
• Operates effectively up to 18 GHz with 50 Ohm impedance matching
• Engineered for high-temperature resilience suitable for harsh environments

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 for the M3933/16-03N to confirm exact electrical tolerances and mechanical dimensions. Ensure compatibility with existing SMA interfaces in your design. Check for any updated environmental compliance certifications or material declarations required for your specific procurement standards before finalizing orders.

Selection Notes

Select this model when a fixed 10 dB attenuation is required within the 18 GHz bandwidth. It is appropriate for applications needing robust performance under extreme temperatures. Consider the non-screened construction if shielding is provided by the host enclosure. Verify that the 2 W power handling meets the system's peak power requirements.

Part Context

This part belongs to the M3933 series of RF attenuators manufactured by Amphenol SV Microwave. These components are classified as RF MIL Spec Connectors and are designed to meet rigorous military standards.
