Comments, with reply, on "Modeling of planar varactor frequency multiplier devices with blocking barriers" by U. Lieneweg et al

The commenter reports that he has conducted a series of measurements for determining the effective series resistance, capacitance, and RC time constant of the back-to-back connected diodes, which exhibit behavior of the effective series resistance and capacitance that is somewhat different than assumed in the commenter´s thesis (UCLA, 1991) or published in the above-titled paper by V. Lieneweg et al. (ibid., vol.40, no.5, p.839-45, May 1992). These results are presented and discussed. In their reply, Lieneweg et al. take issue with some of the commenter´s points and defend their results.<>
