Abstract: A switch matrix structure for planar circuitry such as printed circuit boards and integrated circuits includes a plurality of signal dividers and a plurality of switches. Each signal divider is configured to receive a corresponding input signal and generate a corresponding plurality of divider output signals. Each switch is configured to receive a corresponding divider output from a corresponding signal divider. Each switch is configured to provide a corresponding output signal such that a plurality of output signals are generated by the plurality of switches. In an example, the plurality of switches are arranged in a column, with a first subset of the plurality of signal dividers on a first side of the column, and a second subset of the plurality of signal dividers on a second side of the column. In an example, such a routing configuration reduces a number of routing layers and/or a number of via transitions.

Abstract: A switch matrix circuit module for routing signals. In an example, the module includes a switch matrix coupled with first and second switches. The switch matrix is configured to receive a plurality of input signals, and output a selected one of the plurality of input signals as a first intermediate signal and another selected one of the plurality of input signals as a second intermediate signal. The first switch receives the first intermediate signal and a first auxiliary signal, and outputs a first output signal, and the second switch receives the second intermediate signal and a second auxiliary signal, and outputs a second output signal. A number of the modules can be coupled together to provide a switch matrix circuit, which can be readily scaled by adding further modules. In an example, the plurality of input signals are radio frequency (RF) signals.
