Which EMC (electromagnetic compatibility) devices are helpful for the design and rectification of radio frequency ablation devices?

The core of EMC design for radio frequency ablation devices lies in filtering and shielding. A low-pass filter must be connected to the output of the radio frequency power amplifier, allowing only the operating frequency to pass through and strongly suppressing higher harmonics. The high-voltage DC power supply for the power amplifier requires a high-performance π-type filter. The entire radio frequency generation unit should be installed in a galvanized steel shielded enclosure with proper grounding. Coaxial cables should be used for connecting the ablation electrodes, with the outer conductor grounded. Signal communication between the control unit and the power unit utilizes fiber optic isolation or a differential isolator with high common-mode rejection ratio.
