CPC H03H 11/12 (2013.01) [H03K 5/1252 (2013.01); H04B 1/0475 (2013.01)] | 16 Claims |
1. A circuit having anti-interference mechanism, comprising:
an amplifier electrically coupled to a power supply through a first amplifier bond wire and to a ground terminal through a second amplifier bond wire, and configured to operate according to the power supply and generate an amplified output signal;
a transformer circuit comprising a transformer configured to perform impedance transformation on the amplified output signal to generate a transformed output signal, and a voltage-stabilizing capacitor configured to suppress second-order harmonics of the amplifier; and
a power-terminal side anti-interference circuit comprising:
a power-terminal side bond wire electrically coupled to the ground terminal; and
a power-terminal side anti-interference capacitor electrically coupled between the power-terminal side bond wire and the first amplifier bond wire, to operate together with the power-terminal side bond wire, so as to filter out a first-order harmonics coupling signal coupled to the first amplifier bond wire by the transformed output signal generated by the transformer circuit.
