M3933/25-03N

Overview

The M3933/25-03N is a radio frequency military specification attenuator manufactured by Amphenol SV Microwave. It belongs to the SMA series and features a male-to-female connector configuration with a 50 Ohm impedance. The component supports a maximum frequency of 18 GHz and provides an attenuation value of 3 dB. Designed for robust performance, it operates within a temperature range of -65°C to +165°C and includes a power rating of 2 W. The unit is supplied in bulk packaging.

Feature Summary

• Provides precise signal attenuation via SMA male-to-female interface
• Operates reliably across extreme temperature environments up to 165°C
• Supports high-frequency applications up to 18 GHz

Applications

• Satellite microwave circuit power level adjustment
• RF test and measurement equipment calibration
• Military communication systems requiring signal reduction

Procurement Notes

Verify the specific datasheet version for the M3933/25-03N to confirm current manufacturing specifications. Ensure compatibility with existing SMA interfaces and check that the 18 GHz frequency limit meets system requirements. Confirm the 2 W power rating is sufficient for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 3 dB attenuation is required within an SMA-based RF chain. It is suitable for applications demanding operation at frequencies up to 18 GHz. Consider the wide operating temperature range if the device will be exposed to harsh environmental conditions. Ensure the male-to-female configuration aligns with the connecting hardware.

Part Context

This part falls under the category of RF MIL Spec Connectors and specifically functions as a space attenuator. These components are designed to fine-tune RF power levels in satellite microwave circuits. The M3933 series represents a line of non-screened attenuators offering reliable performance in demanding aerospace and defense applications.

Replacement Considerations

Check for other M3933/25 variants with different attenuation values or screened configurations if signal characteristics differ. Verify cross-compatibility with standard SMA connectors from other manufacturers while ensuring impedance and frequency limits remain consistent.
