M3933/25-59N

Overview

The M3933/25-59N is a radio frequency attenuator manufactured by Amphenol SV Microwave, designed for high-reliability applications. It features an SMA connector interface with male-to-female configuration and operates within a frequency range of 0 Hz to 18 GHz. The component provides a precise attenuation value of 0.5 dB at a characteristic impedance of 50 Ohms. It supports a power rating of 2 Watts and functions reliably across an operating temperature range from -65 °C to +165 °C. This non-screened unit is packaged in bulk.

Feature Summary

• Provides precise 0.5 dB signal attenuation for RF circuit calibration
• Supports operation up to 18 GHz frequency range
• Rated for 2W power handling capacity
• Operates within extended military-grade temperature limits

Applications

• RF test and measurement equipment calibration
• Military communication systems signal conditioning
• Aerospace electronic subsystems
• High-frequency circuit protection and level adjustment

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm the exact attenuation tolerance and connector gender configuration. Ensure that the procurement specifications match the required 50 Ohm impedance and 2W power rating for the intended application environment. Confirm compliance with MIL-Spec standards if required for defense or aerospace projects.

Selection Notes

Select this component when a low attenuation value of 0.5 dB is required for SMA interfaces in high-frequency environments. Consider the 18 GHz upper frequency limit and 2W power handling capability as primary constraints. Evaluate the non-screened construction against electromagnetic interference requirements and verify temperature stability needs against the specified operational range.

Part Context

This model belongs to the M3933 series of RF military specification connectors produced by Amphenol SV Microwave. The series includes various attenuator configurations with different attenuation values and connector types. The M3933/25-59N specifically utilizes the SMA interface standard, distinguishing it from other series members that may use 2.92mm or 3.5mm connections.
