Abstract
In this paper, -15 dB branch-line hybrid was realized. In the case of-15 dB coupling power, the characteristic impedances of transmission lines were 49.20 Omega and 276.689 Omega and it was discussed to realize the high characteristic impedance of 276.689 Omega using coupled transmission lines. Using the method suggested, the problem how to realize the high characteristic impedance of 90deg transmission lines will be solved.
