Abstract

A wireless transceiver coupled to a human interface device (HID) having a first coil is provided. The wireless transceiver includes a control module, a port, and a second coil. The control module includes a radio frequency (RF) unit, a conversion unit, and an electricity power unit. The RF unit is used to receive a RF signal outputted from the HID.

The conversion unit coupled to the RF receiving unit is used to convert the RF signal to a data packet which is in accordance with the HID. The electricity power signal provides electricity power to the control module by the port. The electricity power unit drives the second coil according to the electricity power signal so that the second coil transmits an electromagnetic wave signal to the first coil of the HID by way of resonance and mutual inductance. Therefore, the wireless transceiver can charge to the HID wirelessly.
