PCB RF probe landing pads for multiline deembedding

摘要

The interface between a probe station and an active or passive component on a printed circuit board is of great importance for RF systems operating in the mm-wave frequency range. The landing pads provide the transition between a coplanar measurement device and a microstrip interface. This paper addresses the design issues of such landing pads focusing on finding the optimal design enabling multiline deembedding with a measurement error better than 0.1dB.
