M3933/25-77S

Overview

The M3933/25-77S is an RF attenuator manufactured by Amphenol SV Microwave. It features SMA male to female connectors and operates within a frequency range of 0 Hz to 18 GHz. The component provides a nominal attenuation of 9.5 dB at a system impedance of 50 Ohms. It supports a power rating of 2W and is designed for use in military specification applications.

Feature Summary

• Provides precise signal attenuation for high-frequency RF systems
• Constructed with durable SMA connector interfaces for reliable interconnection
• Designed to meet rigorous military specification standards

Applications

• Military communication equipment signal conditioning
• Test and measurement instrumentation setups
• High-frequency circuit protection and level adjustment

Procurement Notes

Verify the specific screening requirements associated with the 'S' suffix against project specifications. Confirm that the 9.5 dB attenuation value aligns with the design requirements for the target application. Ensure compatibility with existing SMA connector types and 50 Ohm system impedance constraints before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 9.5 dB attenuation is required within the 18 GHz bandwidth. Consider the 2W power handling capability for thermal management. Evaluate the SMA interface type against mating hardware. Compare against other values in the M3933/25 series if different attenuation levels are needed.

Part Context

This part belongs to the M3933 family of RF attenuators from Amphenol SV Microwave. These components are engineered for robust performance in demanding environments. The series offers various attenuation values while maintaining consistent electrical characteristics across the product line.

Replacement Considerations

M3933/25-77N serves as a parameter-equivalent non-screened alternative.
