Procurement Notes

Verify the specific suffix 'N' indicates the correct connector gender and material specification as defined in the official datasheet. Confirm that the MIL-DTL-M3933 compliance meets your program's quality requirements. Check for RoHS non-compliance status if environmental regulations apply to your assembly process. Ensure the 2W power rating aligns with your system's thermal management capabilities.

Selection Notes

Select this model when a precise 24.5 dB attenuation is required within the DC to 18 GHz bandwidth. The SMA interface suits applications needing standard coaxial connections. Consider the 2W power handling limit for high-power signal paths. Verify that the inline module form factor fits your mechanical constraints compared to panel-mount alternatives.
