ABSTRACT:
A radio-frequency switch of planar construction for connecting N input signals to M output signals in a broadcast switch mode or a matrix switch mode. The switch includes a single substrate or circuit board (49) and M output switches (50) disposed in a row on one face of the board, each output switch having N input ports. In the broadcast mode, there are N rows of distributed power dividers (such as 60, 62, 64 and 66), each row providing M outputs from a single input port, the outputs being connected by conductors (such as 90) to the output switches (50). The conductors effecting these cross-connections are formed for the most part on the reverse face of the circuit board, to avoid intersection between the cross-connections and the distributed power dividers. In the matrix mode, the power dividers are replaced by switches (110).
