Novel Transmission Line for 40 GHz PCB Applications

One challenge meeting multi-terabit data flow requirements in advanced routers and servers is squeezing more bandwidth out of traditional methods and materials. The integrity of the signal path is only as good as its narrowest bandwidth components, whether a connector, a trace, or SMT pads acting as 'speed bumps' in the signal path (...)

In this paper, we discuss an electromagnetics based approach to transmission line design, and then explore a novel printed transmission line, Periodic Micro Transmission Line (PMTL™, Patents Pending), with improved signal integrity to 40 GHz.
