Pro: Easy to Implement, Very Low Loss, Isolated, Planar. Con: Narrowband, Physically Large. This is the easiest way to make a 90 degree phase shift in a microstrip microwave circuit. It consists of a ring illustrated below. The insertion and return losses can be made perfect, though only over a small bandwidth: masosaur The important conclusions include: Relative port phase shift is independent of coupler length. Phase shift is affected by mode impedances. Maximum coupling occurs at BL = π/2 radians = 90deg. Good port match and isolation requires Z Ø = ( Z E Z O ) 1/2. High isolation requires mode line phase shifts to be equal. jim dumaswvu kansas tvbaptist primary care login This paper presents a class of wideband 180° hybrid (rat race) couplers implemented by parallel-strip line.
