A switching circuit (2) consisting of CTD lines (p1,q1,p2,q2,p3,q3) is specified in which the properties characteristic for non-unidirectional microwave lines (FIG. 1) are also retained for CTD switching circuits (FIG. 2). To that end, CTD lines (for example, p1,q1) exhibiting mutually opposing conducting directions are combined into a line pair and each incoming line (p1) is connected with each out-going line (q1). The connection ensues partially via CTD lines (c1+c1') and, for the other part, via a galvanic line (L1). Such switching circuits can be employed for the construction of CTD filters with steepness-increased transmission characteristic and also for the construction of correcting circuits.
