Patent ID: 11881639
Assignee: SHENZHEN ZHIYONG ELECTRONICS CO., LTD.
Field: Telecommunications (Electrical engineering)
Classification: CPC G  H | IPC H

Claim 12:
13. The signal isolation and transmission device of claim 4, wherein the high-frequency amplitude modulation circuit comprises:
a voltage regulating circuit and an amplitude modulation circuit;
an output end of the voltage regulating circuit is connected with an input end of the amplitude modulation circuit, and an output end of the amplitude modulation circuit is connected with the first H-field antenna;
when the high-frequency amplitude modulation circuit is connected with a device to be tested, the voltage regulating circuit receives a signal to be tested output by the device to be tested, and regulates the signal to be tested into a positive signal, then the positive signal is transmitted to the amplitude modulation circuit, the amplitude modulation circuit modulates the positive signal onto a high-frequency carrier signal to obtain a first high-frequency modulation signal, and transmits the first high-frequency modulation signal to the first H-field antenna.
