Electromagnetic wave charge management circuit and electromagnetic wave charge management method

An electromagnetic wave charge management circuit used for a receiver device, the electromagnetic wave charge management circuit comprising:

• an antenna to receive an electromagnetic wave signal;
• a filtering unit electrically connected to the antenna to filter the electromagnetic wave signal received by the antenna;
• a converting unit electrically connected to the filtering unit to convert the electromagnetic wave signal filtered by the filtering unit into a direct current voltage;
• a charging unit electrically connected to the converting unit to provide the direct current voltage generated by the converting unit to an internal power supplier of the receiver device;
• and
• a controlling unit electrically connected to the filtering unit and the charging unit to transmit a first control signal that is for controlling the filtering unit to filter the electromagnetic wave signal, and a second control signal that is for controlling the charging unit to provide the direct current voltage generated by the converting unit to the internal power supplier.
