| Abstract: | This paper presents a simple extension of the Chebyshev quarter-wave multisection transformer synthesis to dual-band operation. The method is a variation of the classical Chebyshev transformer design procedure, using a suitable 2nd-order trigonometric polynomial as the argument of the Chebyshev polynomial. As compared to a single-band Chebyshev transformer encompassing both required passbands, the proposed design yields significantly better performance. © 2003 Wiley Periodicals, Inc.
