Abstract
A switch circuit, a control circuit, a grounding wire and a control wire are formed on a substrate. The switch circuit connects an antenna terminal with one of multiple high frequency terminals. The control circuit outputs a control signal to the switch circuit. The grounding wire is disposed between the switch circuit and the control circuit and extends from a location proximate to an edge of the substrate to a location proximate to an opposite edge of the substrate. The control wire that carries the control signal is disposed between one end of the grounding wire and an edge of the semiconductor substrate.

A high frequency semiconductor switch, comprising:
- a switch circuit on a substrate, configured to connect an antenna terminal to a selected one of multiple high frequency terminals;
- a control circuit on the substrate and configured to output a control signal for controlling selection of the high frequency terminal by the switch circuit;
- a grounding wire disposed between and apart from the switch circuit and the control circuit, the grounding wire extending from a first ground terminal located proximate to a first substrate edge to a second ground terminal located proximate to a second substrate edge opposite the first substrate edge;
- and
- a control wire for carrying the control signal, disposed between an end of the grounding wire connected to the first ground terminal and the first substrate edge.
A high frequency semiconductor switch, comprising:
- a substrate with a first face having a first edge and a second edge opposite the first edge;
- a switch circuit formed on the first face in a switch circuit region located between the first edge and the second edge;
- a control circuit formed on the first face in a control circuit region located between the first edge and the second edge and to not overlap with the switch circuit region, the control circuit being configured to output a control signal for controlling an operation of the switch circuit;
- a grounding wire formed on the first face between the control circuit region and the switch circuit region, the grounding wire extending from a first location that is proximate to the first edge to a second location that is proximate to the second edge such that grounding wire is closer to the first edge and the second edge than each of the switch circuit region and the control circuit region;
- and
- a control wire for carrying the control signal output from the control circuit to the switch circuit, the control wire having a portion disposed between the first edge and the first location.
