The paper shows that any arbitrary delay characteristic of a commensurate microwave network which supports a T.E.M. mode of propagation, may be realized by means of a transformerless, coupled-line network within an arbitrary additive constant. The realization procedure presented is based upon the synthesis of microwave C-type and D-type all-pass sections. Synthesis procedures are also developed for the direct realization of a complete all-pass network which include interdigital line structures. The application of microwave all-pass networks to the phase correction of conventional microwave filters and to the construction of delay networks with linear delay characteristics is also presented.
