Abstract:
1. An electronic device comprising: a connector for connecting a sensor; a first signal processing circuit which receives an input of sensor data from the sensor through the connector and forms transmission data which is a digital signal from the sensor data; a second signal processing circuit which converts the transmission data from the first signal processing circuit into a high-frequency signal; an input-output circuit which receives the high-frequency signal and outputs through an antenna; and a board which has a first surface on which the connector and the first signal processing circuit are mounted and a second surface on which the second signal processing circuit and the input-output circuit are mounted, wherein the first and the second surfaces form a signal path connecting two sides of the board and folding back between the first signal processing circuit and the second signal processing circuit, and the connector is mounted on the corresponding side of the board from the input-output circuit.
