Abstract :
This paper proposes a methodology that, starting from a set of calibration measurements picked up at the external ports, allows the de-embbeding of a multi-port transition and the determination of its representative matrix. With this methodology the coupling between internal versus external ports are supposed symmetrical. This hypothesis together with the use of exponential mapping and Baker-Campbell-Hausdorff allows the use of only three standards for the characterization of the multi-port transition. The proposed methodology is applied to the identification of the QFN16 package.
