M3933/25-68N

Overview

The M3933/25-68N is a fixed RF attenuator manufactured by Amphenol SV Microwave. It utilizes SMA connectors with a male-to-female configuration. The component operates within a frequency range of DC to 18 GHz and provides a nominal attenuation value of 5 dB. It features a 50 Ohm impedance rating and supports a maximum power handling capacity of 2 Watts. The unit is designed for non-screened applications and is supplied in bulk packaging.

Feature Summary

• Fixed attenuation performance at 5 dB
• SMA male to female interface
• Operates up to 18 GHz
• Non-screened construction

Applications

• RF signal level reduction
• Military specification interconnect systems
• Test and measurement equipment
• Microwave circuit protection

Procurement Notes

Verify the specific suffix 'N' indicates non-screened construction, as screened variants exist. Confirm SMA gender orientation matches system requirements. Ensure operating frequency does not exceed 18 GHz. Validate power ratings against peak signal levels. Check RoHS compliance status if required.

Selection Notes

Select this model when a 5 dB fixed loss is required in an SMA environment. Consider the 18 GHz upper frequency limit for bandwidth needs. Evaluate the 2 W power rating for thermal management. Compare against screened versions if EMI shielding is necessary. Verify connector gender compatibility with mating hardware.

Part Context

This part belongs to the M3933 series of connectorized attenuators from Amphenol SV Microwave. The series includes various attenuation values and connector types. The M3933/25 variant specifically denotes SMA interfaces. Other suffixes indicate different attenuation levels or screening conditions.

Replacement Considerations

FAQ

What is the difference between M3933/25-68N and M3933/25-68S?

The 'N' suffix indicates a non-screened attenuator, while the 'S' suffix denotes a screened version providing electromagnetic interference protection.

Is this component suitable for frequencies above 18 GHz?

No, the specified maximum operating frequency is 18 GHz. Performance beyond this limit is not guaranteed.
