M3933/25-72N

Overview

The M3933/25-72N is an RF fixed attenuator manufactured by Amphenol SV Microwave. It operates within a frequency range of 0 Hz to 18 GHz and provides a nominal attenuation of 7 dB. The component features SMA male-to-female connectors and maintains a 50 Ohm impedance. It supports a maximum power rating of 2 W and functions reliably between -65 °C and +165 °C. Packaged in bulk, this inline module is designed for high-frequency signal management.

Feature Summary

• Provides precise 7 dB signal attenuation for RF applications
• Operates with SMA male to female interface connections
• Supports continuous power handling up to 2 Watts
• Maintains stable performance across extended temperature ranges

Applications

• RF test and measurement equipment calibration
• Signal conditioning in microwave communication systems
• Attenuation requirements in radar subsystems

Procurement Notes

Verify the specific datasheet version for the M3933/25-72N to confirm current manufacturing specifications and compliance status. Ensure that the SMA connector gender and mating compatibility align with the target system design. Cross-reference the 7 dB attenuation tolerance and 2 W power rating against application requirements to prevent signal degradation or thermal issues during operation.

Selection Notes

Select the M3933/25-72N when a fixed 7 dB reduction is required at frequencies up to 18 GHz. The SMA interface suits standard coaxial setups, while the 2 W rating handles moderate power levels. Consider the operating temperature range if deployed in harsh environments. Verify impedance matching to ensure minimal reflection in 50 Ohm systems.
