A radio frequency generator, comprising an input voltage unit (10), an intelligent power supply unit (20), a voltage acquisition unit (30), a power amplifier unit (80), an output unit (90), a load unit (100), a current acquisition unit (40), a processor unit (50), a signal sending and driving unit (60) and an input control unit (70). The radio frequency generator combines the advantages of a high-frequency electrotome and radio frequency ablation equipment, can be applied to cutting and coagulation of target tissue and can also be applied to ablation or treatment of target tissue. The radio frequency generator is strong in universality and can be produced and manufactured as a standard component and part. Different medical radio frequency manufacturers can produce and manufacture their own products through changing a small number of peripheral circuits or software so as to meet the clinical demands of different clients and different departments.
