M3933/30-13N

Overview

The M3933/30-13N is a fixed RF attenuator manufactured by Amphenol SV Microwave, designed for high-frequency applications up to 32 GHz. It features a 2.92mm female-to-male connector configuration with a nominal attenuation value of 13 dB. The component operates within a frequency range of DC to 32 GHz and maintains a standard impedance of 50 Ohms. It has a power rating of 2 Watts and is constructed as a non-screened unit. The device supports an operating temperature range from -65°C to +165°C and is supplied in bulk packaging.

Feature Summary

• Provides precise signal attenuation for microwave circuits using a 2.92mm interface
• Engineered for high-temperature stability with operation up to +165°C
• Supports high-power handling capabilities rated at 2 Watts

Applications

• Satellite communication systems requiring precise RF power control
• Microwave test and measurement instrumentation setups
• Defense and aerospace radar subsystems

Procurement Notes

Verify the specific suffix 'N' indicates a non-screened construction variant when sourcing replacements. Confirm that the 2.92mm gender orientation matches the system requirements, as this model specifies female-to-male connectivity. Ensure environmental specifications align with the intended operational temperature range and power levels before finalizing procurement orders.

Selection Notes

Select this component when a fixed 13 dB attenuation is required within the 32 GHz bandwidth. The 2.92mm interface offers superior performance compared to SMA connectors at higher frequencies. Consider the non-screened design if external shielding is provided by the host enclosure or if weight constraints are critical for the application.

Part Context

This part belongs to the M3933 series of connectorized attenuators from Amphenol SV Microwave. These components are widely used in military and aerospace sectors due to their rugged construction and wide frequency coverage. The series includes various attenuation values and connector types to support diverse RF circuit needs.

Replacement Considerations

M3933/30-13S is the screened equivalent variant. Verify if shielding requirements differ between the current design and potential substitutes.
