Abstract
A high-frequency switch module includes a switch element, high-frequency circuits, and a GND circuit. The switch element includes an antenna port, switch ports, and an FET switch. The FET switch switches connection between the switch ports and the antenna port. The high-frequency circuits connect any of the switch ports to a signal processing circuit. In the GND circuit, the switch port, which is not connected to the high-frequency circuits, is directly connected to a GND electrode.
