Abstract
A wireless transceiver device and matching circuits thereof are provided. In the wireless transceiver device, a first matching circuit is electrically coupled to an antenna and a transmission circuit. In the first matching circuit, a first capacitor is electrically coupled to the antenna and a first switching component, the first switching component is electrically coupled to a reference voltage, a first active component having a first threshold voltage is coupled in parallel with the first switching component, a first inductor of an inductor pair is electrically coupled to the antenna and the reference voltage, and a second inductor of the inductor pair is electrically coupled to the transmission circuit. When the voltage across the first active component is greater than the first threshold voltage, the first active component is turned on, thus reducing the voltage across the first switching component to protect the first switching component.
