M3933/25-46N

Overview

The M3933/25-46N is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It features SMA connectors and provides a nominal attenuation of 20 dB. The device operates within a frequency range of 0 Hz to 12.4 GHz, with a maximum rated power of 2 W. It maintains a characteristic impedance of 50 Ohms. The unit is designed for in-line module applications and supports an operating temperature range from -65°C to +165°C.

Feature Summary

• Provides precise 20 dB signal attenuation for RF systems
• Supports operation up to 12.4 GHz frequency range
• Handles continuous wave power ratings of 2 W
• Constructed for high-temperature environments up to 165°C

Applications

• Military and aerospace RF signal conditioning
• Test and measurement equipment calibration
• Communication system power level adjustment

Procurement Notes

Verify the specific suffix 'N' indicates non-screened construction as per manufacturer documentation. Confirm that the 12.4 GHz upper frequency limit applies to your specific application requirements rather than the broader 18 GHz family capability. Ensure environmental specifications meet operational thermal demands. Cross-reference datasheets for exact VSWR and insertion loss values prior to integration.

Selection Notes

Select this component when a fixed 20 dB attenuation is required at frequencies up to 12.4 GHz. The 50 Ohm impedance matches standard RF infrastructure. Consider the extended temperature range if operating in harsh environments. Verify connector gender compatibility for male-to-female or inline configurations based on system design needs.

Part Context

This part belongs to the M3933/25 series of connectorized attenuators. It shares the SMA interface and general form factor with other variants in the lineup. Differentiation lies primarily in the specific attenuation value and frequency cutoff characteristics defined by the model number suffix.

Replacement Considerations

M3933/25-46S is the screened equivalent variant. Other models in the M3933/25 series offer different attenuation levels but share similar physical interfaces.
