M3933/25-65N

Overview

The M3933/25-65N is a fixed RF attenuator manufactured by Amphenol SV Microwave, designed for high-frequency applications. It features SMA male-to-female connectors and operates within a frequency range of DC to 18 GHz. The component provides an attenuation value of 3.5 dB with a nominal impedance of 50 ohms. It is rated for a maximum power handling capacity of 2 watts and functions reliably across an operating temperature range from -65°C to +165°C.

Feature Summary

• Provides precise signal attenuation in the 3.5 dB range for RF circuit management.
• Utilizes robust SMA connector interface for secure male-to-female interconnection.
• Engineered for wide thermal stability suitable for demanding environmental conditions.

Applications

• Satellite communication systems requiring stable RF power levels
• Test and measurement instrumentation setups
• Microwave circuit calibration and signal conditioning

Procurement Notes

Verify the specific datasheet version for the M3933/25-65N to confirm exact mechanical dimensions and material specifications prior to integration. Ensure that the SMA connector gender and mating requirements align with the target system design. Cross-reference the power rating and frequency response against the application's peak load conditions to prevent performance degradation or component failure during operation.

Selection Notes

Select this component when a fixed 3.5 dB attenuation is required at frequencies up to 18 GHz. The SMA interface offers compatibility with standard RF test equipment and modular designs. Consider the 2-watt power rating and extended temperature range if the deployment environment involves high thermal loads or extreme cold, ensuring the device meets the specific impedance matching needs of the 50-ohm system architecture.
