Analyzing the DDR Simulation Results
After looking in past months at critical signal integrity concerns that engineers face designing the DDR bus, and points to consider while setting up the simulation, this month the author discusses what to look for in the results of the simulation.

Choosing Copper Foils for High-Frequency PCBs
Perhaps surprisingly, the same type of electrodeposited copper processed with two different treatments can yield two different levels of circuit performance. Thinner materials for microwave boards benefit from smooth surfaces to decrease insertion loss.
