Abstract :
Tables are presented for the design of TEM-mode asymmetric multi-element coupled-transmission-line directional couplers, having a very broad-band Chebyshev equal-ripple coupling response. Coupler designs of 2 to 6 elements having bandwidths up to 20:1 and mean couplings of 3, 6, 10, 15 and 20 db are tabulated.
