M3933/16-19N

Overview

The M3933/16-19N is a fixed RF attenuator manufactured by Amphenol SV Microwave, designed for military specification applications. It features SMA connectors with a jack-to-plug interface configuration. The component operates within a frequency range of DC to 18 GHz and maintains a characteristic impedance of 50 Ohms. It provides a nominal attenuation value of 2.5 dB. The unit is rated for a maximum power handling capacity of 2 W and functions reliably across an operating temperature range from -65°C to +165°C.

Feature Summary

• Military-grade construction compliant with MIL-Spec standards
• Fixed attenuation design for precise signal level control
• High-temperature capability suitable for harsh environments

Applications

• Satellite communication systems
• Radar equipment signal conditioning
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'N' indicates the non-screened variant when sourcing replacements. Confirm that the jack-to-plug orientation matches the system requirement, as screened versions may differ in shielding characteristics. Ensure the manufacturer is identified as Amphenol SV Microwave to guarantee compliance with the original military specifications.

Selection Notes

Select this component when a fixed 2.5 dB reduction is required at frequencies up to 18 GHz. The 50 Ohm impedance ensures compatibility with standard RF transmission lines. Consider the high-temperature rating if the installation environment exceeds typical commercial limits. Verify that the non-screened construction meets the electromagnetic interference requirements of the specific application.
