Abstract :
A class of lossless symmetrical lumped-element four 1-1 port couplers with maximally flat coupling is presented. The four-port circuits can be realized using a new synthesis procedure for symmetrical four 1-1 port networks. The even- and odd-mode circuits are symmetrical lumped-element lattice networks
