Radio frequency switch and high-speed switch box

The invention relates to a radio frequency switch and a high-speed switch box. The radio frequency switch comprises a radio frequency switch shell. A periphery of the radio frequency switch shell is provided with a radio frequency connector and a wiring terminal. A top of the radio frequency switch shell is provided with a heat dissipation seat, and the heat dissipation seat is provided with a plurality of vertically arranged cooling fins. Heat generated by a solid-state radio frequency switch is conducted to a case shell through the heat dissipation seat in a conduction heat dissipation modeand then is further dissipated through a galvanized steel sheet on an inner wall of a darkroom so that a heat dissipation area and efficiency are greatly increased. Through improving arrangement and distribution of radio frequency switches in a high-speed switch box, double-layer arrangement and distribution is performed on the radio frequency switches and a ventilation cavity is increased.
