Abstract :
The problem of designing a maximally flat low-pass, high-pass reactance-ladder diplexer with adjustable crossover attenuation and variable bandwidth is considered. The authors present a reasonably complete theoretical and practical solution based on a new and simple algebraic formulation. In particular, the desired solution is shown to be related to the existence of a strictly Hurwitz polynomial that satisfies certain divisibility conditions
