http://repository.bilkent.edu.tr/handle/11693/49637 WebThis phase shift is both broadband (unlike a delay line) and relative (between the outputs). Marki quadrature hybrids are created by building a backwards wave coupler (similar to our stripline directional couplers) with a 3 dB coupling value and creating equal power outputs (for other methods and their merits or demerits, see this tech note).

WebAug 1, 1996 · Typically, Lange couplers are realized in a microstrip, coplanar wave-guide or some other nonhomogeneous medium. In this case, the even- and odd-mode phase velocities are unequal, and it is difficult to define a quarter-wavelength precisely.
