Title Kcalc: Microwave Office script to produce Klopfenstein-tapered multisection impedance transformers
Abstract/Summary This MWO script produces multisection tapered impedance transformers, with the Klopfenstein tapering function. It can easily be modified to produce tapers with other characteristic functions, as well as tapered couplers. A range of transformer parameters can be specified, including the required return loss. This script is intended not only as a design tool, but also as an educational tool as it illustrates many aspects of Microwave Office scripting.

References [1] Theoretical foundation used to produce this script is contained in Sec. 5.8 ("Tapered Lines"), pp. 288-297, of "Microwave Engineering" (2nd edition) by D. M. Pozar, published in 1998 by John Wiley & Sons, Inc. [2] Theoretical framework indicating how to make tapered coupled line hybrids can also be found in the book from [1], Sec. 7.8, pp. 401-411. [3] The way in which Klopfenstein taper impedances are numerically calculated is explained in M. A. Grossberg, "Extremely Rapid Coumputation of the Klopfenstein Impedance Taper," Proc. IEEE, vol. 56, pp. 1629-1630, September 1968.
