Abstract :
A broadband de-embedding method for two-port transmission parameters is presented. This method is based on the computation versus frequency of the monotonous phase variations of the positive travelling wave ??. The main advantage over already published methods is that the physical length of lines involved in de-embedding of the two port transmission (S21 and S12) parameters is not needed.
