Abstract :
Tables are presented for the design of asymmetric nonuniform-coupled transmission-line directional couplers, having a high-pass Chebyshev equal-ripple coupling response. The coefficients of the continuously tapered coupling factor represented as a polynomial of sixth order are tabulated for mean couplings of -3, -6, -8.34, -10, and -20 dB and for a given ripple of the high-pass coupling response.
