Manufacture of novel double-side direct thru kit with nonexchange layer structure base on general PCB process

摘要

In this paper, the novel double-side direct thru kit with non-exchange layer structure is presented. The thru element of open-short-load-thru (SOLT) had been realized base on co-planar waveguide structure by the proposed manufacture flow. The results of thru element are measured by Cascade ACP type RF probe in 3D double-side measurement system. The operating bandwidth is 13.7 GHz with upon −0.2dB forward insertion loss and below −20dB return loss.
