... Linear Power Amplifier NOTE: REFER TO MAX2242 EV KIT DATA SHEET FOR DETAILED LAYOUT INFORMATION. UCSP reliability performance shows that it is capable of performing reliably through environmental stresses. Users should also be aware that as with any intercon- nect system there are electromigration-based current limits that, in this case, apply to the maximum allowable current in the bumps ...
