Title:
FLEXIBLE MICROWAVE SWITCH MATRIX
Document Type and Number:
Japanese Patent JP2000278001
Kind Code:
A
Abstract:

To obtain a microwave switch matrix with a simple configuration where signals are highly isolated.

This switch matrix is provided with a plurality of input lines 22 that respectively receive an input signal, a plurality of output lines 26 that output an output signal, and a plurality of nodes 20 each of which connects the input line 22 to a prescribed output line 26. Each node 20 is provided with a switch 30, an input coupler 28 and an output coupler 32. The input coupler 28 connects the input line 24 to the switch 30, the output coupler 32 connects the output line 26 in a way that the switch 30 couples the input line 22 with the output line 26. The input coupler 28, the output coupler 32 and the switch 30 are configured on a printed circuit board with a double side faces to form a plurality of waveguide transmission lines on a same plane.
