M3933/25-60S

Overview

The M3933/25-60S is a screened RF attenuator manufactured by Amphenol SV Microwave. It utilizes SMA connectors with a male-to-female configuration and operates within a frequency range of 0 Hz to 18 GHz. The component provides a fixed attenuation value of 1 dB at a characteristic impedance of 50 Ohms. It supports a maximum power rating of 2 W and functions reliably across an operating temperature range from -65 °C to +165 °C.

Feature Summary

• Screened construction for enhanced environmental protection
• Fixed 1 dB attenuation in a compact inline module design
• Compatible with standard SMA connector interfaces

Applications

• Military radio systems requiring precise signal reduction
• Test and measurement instrumentation setups
• High-frequency communication equipment calibration

Procurement Notes

Verify the specific suffix 'S' indicates the screened variant when sourcing replacements. Confirm that the SMA gender configuration matches the male-to-female requirement for your circuit topology. Ensure the 1 dB attenuation specification aligns with system loss budgets. Validate that the 2 W power handling capacity meets operational peak levels. Check compatibility with MIL-spec connector standards for integration.

Selection Notes

Select this model for applications demanding stable, low-loss attenuation up to 18 GHz. The screened housing offers superior shielding compared to non-screened alternatives. Consider the wide temperature range for harsh environment deployments. Verify that the SMA interface fits existing panel or cable assemblies without adapter requirements.

Part Context

This component belongs to the M3933 series of RF attenuators designed for military specifications. It complements other variants like the M3933/25-61S which offers higher attenuation values. The series provides reliable performance for defense and aerospace electronics where consistent signal integrity is critical.
