M3933/14-11S

Overview

The M3933/14-11S is a connectorized RF attenuator manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It features SMA connectors and provides an attenuation value of 8 dB. The component operates within a frequency range of 0 Hz to 12.4 GHz with a 50 Ohm impedance. It has a power rating of 2 W and functions across a temperature range of -55°C to +125°C.

Feature Summary

• Provides fixed 8 dB signal attenuation for RF applications
• Utilizes SMA male/female connector interface
• Designed for high-frequency operation up to 12.4 GHz
• Constructed as an in-line module for series integration

Applications

• RF signal level adjustment in communication systems
• Test and measurement equipment calibration
• Military and aerospace electronic subsystems
• Shielded circuit protection and signal conditioning

Procurement Notes

Verify part authenticity through authorized distributors or direct manufacturer channels. Confirm specific suffix designations match project requirements, as variations may exist between screened and standard versions. Check current availability status due to potential lead time fluctuations associated with specialized military-grade components.

Selection Notes

Select this model when an 8 dB fixed attenuation is required at 50 Ohms. Ensure SMA compatibility with existing interconnects. Verify that the 2 W power handling capacity meets system peak power demands. Confirm environmental ratings align with operational temperature constraints.

Part Context

This component belongs to the M3933/14 series of shielded attenuators. It is designed for rugged environments requiring reliable performance. The product line supports various attenuation values within the same form factor, allowing for standardized mechanical integration across different signal processing needs.

Replacement Considerations

M3933/14-11N serves as a functional equivalent with N-type connectors instead of SMA. Other M3933/14 variants offer different attenuation levels but share similar electrical characteristics and mounting styles.
