Abstract :
A coupled-line phase shifter can be decomposed in two lines of stepped characteristic impedances, interconnected by a 180° hybrid. This network permits phase responses which cannot be realised with coupled lines. Practical simplifications are possible by omitting one of the two lines or by using a 90° hybird.
