Abstract (en)
[origin: EP1014468A2] A planar microwave switch matrix including a plurality of inputs (22) for receiving input signals, a plurality of outputs (26) for transmitting output signals, and a plurality of nodes (20) connecting the inputs to the outputs. Each node (20) includes a switch (30), an input coupler (28) and an output coupler (32). The input and output couplers connecting input lines to output lines such that any input can be connected through a switch to any output. The planar microwave switch matrix is formed on a dual-sided circuit board to form a plurality of co-planar waveguide transmission lines. The layout of the microwave switch matrix allows any combination of input lines and output lines to be connected at a given time, while providing sufficient signal isolation to prevent interference. <IMAGE>
