M3933/16-44N

Overview

The M3933/16-44N is a fixed RF attenuator manufactured by Amphenol SV Microwave, designed for military-grade applications. It operates within the SMA series and supports frequencies from DC to 18 GHz with a nominal impedance of 50 Ohms. The component provides an attenuation value of 19 dB and handles a power rating of 2 Watts. It features a female-to-male connector configuration and is classified as a nonscreened unit. The device is rated for operation between -65°C and +165°C.

Feature Summary

• Provides precise signal attenuation in high-frequency RF circuits
• Supports extended temperature ranges suitable for harsh environments
• Utilizes robust SMA interface for reliable connectivity

Applications

• Satellite microwave circuit power level adjustment
• Military RF system signal conditioning
• Test and measurement equipment calibration

Procurement Notes

Verify the specific datasheet version for the M3933/16-44N to confirm exact electrical tolerances and mechanical dimensions prior to integration. Ensure that the nonscreened classification aligns with the electromagnetic interference requirements of the target assembly. Cross-reference the manufacturer's latest documentation to validate compliance with current environmental standards and material specifications.

Selection Notes

Select this component when a fixed 19 dB attenuation is required at frequencies up to 18 GHz. The nonscreened design is appropriate for applications where shielding is provided by the housing or chassis. Consider the 2W power handling capability and the wide operating temperature range when evaluating suitability for demanding operational conditions.

Part Context
