Simultaneous wireless information and power transfer device and method based on the modulation of power supply ripple of magnetron

A SWIPT (simultaneous wireless information and power transfer) device based on magnetron modulation of power supply ripple of magnetron, the SWIPT device comprising a magnetron power supply, a magnetron, an IF (intermediate frequency) signal generator, a first capacitor, a first inductor, a second inductor, a third inductor and a fourth capacitor, wherein:

• one end of the magnetron power supply is connected with one end of a first cathode power line;
• another end of the magnetron power supply is connected with one end of a second cathode power line;
• another end of the first cathode power line and another end of the second cathode power line are connected with two ends of a cathode of the magnetron respectively;
• one end of the first capacitor is connected with the IF signal generator;
• another end of the first capacitor is connected with the another end of the first cathode power line;
• the first inductor is provided between the one end and the another end of the first cathode power line;
• the second inductor is provided between the one end and the another end of the second cathode power line;
• one end of the third inductor is connected with the IF signal generator, and another end of the third inductor is grounded;
• one end of the fourth capacitor is connected with the one end of the first cathode power line, and another end of the fourth capacitor is grounded;
• the SWIPT device further comprises a fifth capacitor, wherein one end of the fifth capacitor is connected with the one end of the second cathode power line, and another end of the fifth capacitor is grounded.
