M3933/14-19N

Overview

The M3933/14-19N is a non-screened RF attenuator manufactured by Amphenol SV Microwave. It utilizes SMA connectors with male-to-female gender configuration and operates at a maximum frequency of 12.4 GHz. The component provides an attenuation value of 14 dB within a 50 Ohm impedance system. It supports a power rating of 2 Watts and functions across a temperature range from -65°C to +165°C.

Feature Summary

• Provides precise signal attenuation for satellite microwave circuit applications
• Features SMA connector interface for reliable interconnect performance
• Designed for high-temperature operation in demanding environments

Applications

• Satellite microwave circuit power level adjustment
• RF test and measurement instrumentation
• Military and aerospace communication systems

Procurement Notes

Verify the specific suffix 'N' indicates the non-screened variant distinct from screened versions like 'S'. Confirm the 14 dB attenuation specification matches the design requirement. Ensure SMA male-to-female orientation aligns with the system topology. Validate that the 12.4 GHz frequency limit suits the operational bandwidth.

Selection Notes

Select this model when a fixed 14 dB attenuation is required at 12.4 GHz. Consider the non-screened construction if shielding is not mandated by the application. Verify compatibility with existing SMA infrastructure. Evaluate thermal management needs given the wide operating temperature range.

Part Context

This component belongs to the M3933 series of space attenuators designed for RF power control. It is part of Amphenol's portfolio of military-grade RF interconnects. The series includes various attenuation values and connector types for diverse microwave applications.

Replacement Considerations

M3933/14-19S is the screened equivalent version. Other M3933 variants offer different attenuation levels or connector configurations.
