Design of x-band mmic 3 db lange couplers

WebBefore we go on, let's point out that a Lange coupler is a 3 dB microstrip coupler that accomplishes the required even/odd impedances for equal split. Julius Lange divided the lines into multiple smaller lines to provide … 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).
