Attenuators Procurement Notes

Verify the specific suffix designation when sourcing replacements, as variations may exist within the product family. Confirm that the required package matches the SC-74A form factor. Ensure compatibility with the 50 Ohm system impedance. Check current availability status as this component may be subject to lifecycle changes or discontinuation notices from the manufacturer.

Attenuators Selection Notes

Select this component when a fixed 10 dB attenuation step is required within a digital control architecture. It is suitable for designs operating below 2.5 GHz where low-cost GaAs solutions are preferred. Consider the 1W power rating for appropriate signal levels. Evaluate the SOT-753 footprint constraints against the PCB layout requirements.
