Attenuators Procurement Notes

Verify the specific datasheet version and manufacturer specifications before procurement. Confirm that the SMA connector gender and mating requirements align with your system design. Ensure the operating environment does not exceed the 4.5W power rating or 18 GHz frequency limit. Check for RoHS compliance status if required by your manufacturing standards. Validate part authenticity through authorized channels to avoid counterfeit components.

Attenuators Selection Notes

Select this model when a fixed 20 dB attenuation is required at frequencies up to 18 GHz. Consider the 4.5W power handling capability against your system's peak and average power levels. The SMA interface dictates connector compatibility; ensure mating cables and adapters match the SMA type. Compare insertion loss and VSWR specifications from the official datasheet against application tolerances. Evaluate thermal management needs based on the power dissipation characteristics.
