the power interface comprises a first connecting part and a second connecting part, wherein the first connecting part is multiplexed into an antenna, and the first connecting part is connected with a low-pass/band-stop filter network;
the radio frequency module is connected with the antenna through a galvanic isolation element;
the power module is connected with the first connecting part through the low-pass/band-stop filter network or connected with the second connecting part.
2. The electronic device of claim 1, wherein the galvanic isolation element comprises a capacitor.
3. The electronic device of claim 1, wherein the radio frequency module comprises a radio frequency processing unit and a matching/band pass filter network, the matching/band pass filter network being connected between the radio frequency processing unit and the galvanic isolation element, the radio frequency processing unit being connected to the power module.
4. The electronic device of claim 3, wherein the radio frequency module further comprises a first guard circuit connecting the radio frequency processing unit and the matching/bandpass filter network.
5. The electronic device of claim 1, wherein the power module comprises a power processing unit and a battery connected to each other, the power processing unit is connected to the first connection via the low pass/band reject filter network, the second connection is connected to ground, and the power processing unit is connected to the radio frequency module.
6. The electronic device of claim 5, wherein the power module further comprises a unidirectional conductive element connected between the power processing unit and the low pass/band reject filter network, the unidirectional conductive element allowing current to flow from the low pass/band reject filter network to the power processing unit.
7. The electronic device of claim 1, wherein the power module comprises a power processing unit and a battery connected to each other, the power processing unit being connected to the second connection portion.
8. The electronic device of claim 7, wherein the power module further comprises a unidirectional conductive element connected between the low pass/band reject filter network and ground.
9. The electronic device of claim 6 or 8, wherein the unidirectional conductive element comprises a diode.
10. The electronic device of claim 1, further comprising a second guard circuit connecting the first connection and the antenna.
