M3933/16-19S

Overview

The M3933/16-19S is a fixed RF attenuator manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It features SMA connectors and provides a nominal attenuation of 2.5 dB. The device operates within a frequency range of 0 Hz to 18 GHz, with a maximum power rating of 2 W. It is designed for an operating temperature range from -55°C to +125°C. The component complies with MIL-DTL-M3933 standards and is classified as a screened QPL product.

Feature Summary

• Complies with MIL-DTL-M3933 military specifications
• Screened Qualified Products List (QPL) status
• SMA male/female connector configuration
• Wideband operation up to 18 GHz

Applications

• Military communication systems
• Aviation radar equipment
• Test and measurement instrumentation
• Defense electronic warfare applications

Procurement Notes

Verify that the specific order includes the 'S' suffix designation, which indicates the screened QPL variant compliant with MIL-DTL-M3933. Confirm that the procurement documentation explicitly references the military qualification status, as standard commercial variants may lack the required screening and traceability. Ensure the supplier provides valid certification of compliance with the specified military standard for defense or aerospace integration.

Selection Notes

Select this model when a precise 2.5 dB attenuation value is required in high-frequency environments up to 18 GHz. The 2 W power handling capability supports moderate signal levels. The wide operating temperature range ensures reliability in harsh conditions. Verify that SMA interface compatibility matches the system architecture before integration.

Part Context

This component belongs to the M3933/16 series of connectorized attenuators. The series offers various attenuation values while maintaining consistent electrical performance across the 0–18 GHz band. The M3933/16-19S represents a specific attenuation step within this standardized family, ensuring interchangeability with other parts in the same series for modular system design.

Replacement Considerations

M3933/16-19N serves as a non-screened equivalent within the same series. Other models in the M3933/16 series provide different attenuation values but share identical form factors and frequency ranges.
