M3933/16-13S

Overview

The M3933/16-13S is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a nominal attenuation of 40 dB with a 50 Ohm impedance. The device operates within a frequency range of 0 Hz to 18 GHz and supports a maximum power rating of 2 Watts. It utilizes SMA connectors in a male/female configuration, housed in an SMA single-row module package. The component is designed for screened applications and complies with military specifications.

Feature Summary

• Provides precise 40 dB signal attenuation for RF systems
• Operates across a wide bandwidth from DC to 18 GHz
• Features durable SMA connector interface for reliable interconnection
• Designed for high-power handling up to 2 Watts

Applications

• Military and aerospace RF signal conditioning
• Test and measurement equipment calibration
• Communication system signal level adjustment
• Shielded electronic assembly integration

Procurement Notes

Verify the specific suffix 'S' indicates screened construction when ordering. Confirm RoHS non-compliance status aligns with project requirements. Check current availability as this item may be produced to order. Ensure SMA gender compatibility (male/female) matches the system design. Validate that the 2W power rating meets the operational thermal limits of the application environment.

Selection Notes

Select this model when a fixed 40 dB attenuation is required at frequencies up to 18 GHz. The SMA interface suits standard coaxial test setups. Consider the 2W power limit for high-power transmission lines. The screened variant offers enhanced isolation for sensitive environments. Verify impedance matching to ensure minimal reflection in 50 Ohm systems.
