Abstract: A high electron mobility transistor (HEMT) includes a channel layer, a plurality of barrier layers, and a p-type semiconductor layer. The barrier layers have an energy band gap greater than that of the channel layer. A gate electrode is arranged on the p-type semiconductor layer. A source electrode and a drain electrode are apart from the p-type semiconductor layer and the gate electrode on the barrier layers. Impurity concentrations of the barrier layers are different from each other in a drift area between the source electrode and the drain electrode.

Abstract: Methods and devices for antenna switching are provided. A wireless signal is transmitted and received through a specific antenna module among a plurality of antenna modules. Status information about each of one or more other antenna modules among the plurality of antenna modules is acquired, when a temperature of the specific antenna module exceeds a predetermined value. The temperature of the specific antenna module is measured through a respective sensor module of a plurality of sensor modules. Each sensor module of the plurality of sensor modules is contained in or disposed adjacent to a respective antenna module of the plurality of antenna modules. The specific antenna module is switched to an antenna module selected from among the one or more other antenna modules, based on the acquired status information.
