Comments on "Characterization of Resistive Transmission Lines by Short-Pulse Propagation"



Dylan F. Williams, Roger Marks


In the above letter, the authors report measurements of the complex propagation constant y of a coplanar waveguide and the application of r to the determination of the characteristic impedance. The authors state that "the same information could, in principle, be obtained with a network analyzer" by the method described in [l]. In fact, these measurements were reported in [l]. Furthermore, the bandwidth of the network analyzer method is broad, with [1] reporting an upper limit of 40 GHz,2 well above the 25-GHz limit reported in the letter.
