    We report an advanced phase compensation principle, which employs combined backward-forward transmission lines having similar frequency dispersion. Various applications of this principle to the design of microwave devices allow for an exceptionally low dispersion in a wide frequency range while keeping the structure very compact and simple compared to conventional solutions. To illustrate the idea, we present the performance of (i) phase shifters, (ii) power dividers and (iii) baluns (complete antenna feeders) built on the reported principle. We support the theoretical estimates by microwave circuit simulations and direct measurements, showing that the novel devices can be easily implemented with simple electronic components.
