Abstract
A switching circuit (2) consisting of CTD lines (p.sub.1,q.sub.1,p.sub.2,q.sub.2,p.sub.3,q.sub.3) 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, p.sub.1,q.sub.1) exhibiting mutually opposing conducting directions are combined into a line pair and each incoming line (p.sub.1) is connected with each out-going line (q.sub.1). The connection ensues partially via CTD lines (c.sub.1 +c.sub.1 ') and, for the other part, via a galvanic line (L.sub.1). 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.
