Millimeter wave frequencies are essential for transferring more data more quickly, but it also requires different packaging technology to minimize loss and drift. That opens up a number of tradeoffs around antenna in package, antenna on package, flexible circuits, and different substrates. Curtis Zwenger, vice president of R&D at Amkor Technology, talks about a host of new challenges ranging from over-the-air testing and cross talk to impedance matching.
