An electronic device is provided. The electronic device includes a housing, a first circuit board, and a first heat sink. The housing forms a receiving space. The first circuit board and the first heat sink are received in the receiving space along the gravity direction. One side of the first circuit board has at least one electronic element. The first heat sink has a first base board and at least first side board. The first base board is arranged adjacent to the first circuit board. The electronic element transferred heat to the first base board. The first side board connects to the first base board, and cooperatively forms a first heat dissipating channel along the gravity direction. The first side board is close to or contacts the housing, so that the heat of the electronic element can be transferred by heat conduction and heat convection to dissipate outside.

Electronic device having electronic components with different temperature specifications

An antenna device and an antenna switch circuit are provided. The antenna device comprises a first antenna, an antenna detection circuit, a switch control circuit, and a controller. The first antenna is configured to transmit an RF signal. The antenna detection circuit comprises an inductor configured to detect a second antenna. The switch control circuit is coupled to the antenna detection circuit and configured to generate a first control signal indicative of the presence of the second antenna upon the detection thereof. The controller is coupled to the first antenna, the antenna detection circuit and the switch control circuit, and configured to receive the first control signal and connect to the second antenna when the first control signal indicates the presence of the second antenna.
