ABSTRACT:
A dynamic electronic switch (10) having n inputs (2) and m outputs (4), where n and m are any positive integers. The electromagnetic signal on any given input (2) may be switched onto any number of outputs (4), but any given output (4) may have no more than one input signal switched thereonto at any given time. Switching nodes (8), comprising at least one switching diode (11, 13, 15) and a directional edge coupler (17) embedded between two parallel ground planes (9, 1) in a planar mother board (5), perform switching at each intersection of an input (2) and an output (4). Each output (4) is mounted on a planar dielectric summer board (6) positioned orthogonal to the mother board (5). The lengths of the extended transmission lines (76) associated with each output (4) are such that when an input signal is switched onto said output (4), the sum of the admittances of the n-1 unswitched extended transmission lines ( 76), measured between an associated summing junction (85) and ground, is substantially equal to zero.
