Procurement Notes

Verify the specific connector gender (jack/plug) and mating interface compatibility before procurement, as datasheet descriptions may vary regarding exact pin configurations. Confirm that the tray packaging aligns with your automated assembly requirements. Ensure the 2W power rating meets your system's thermal and electrical demands at the target operating frequency.

Selection Notes

Select this model when a fixed 2 dB reduction is required in the 32 GHz band. Compare against other M3933 series variants if different attenuation values or connector types are needed. Consider the SMA interface constraints versus higher-performance alternatives like 2.92mm if superior VSWR is critical for your specific application environment.
