RFGM series generator modules

RFGM-series are medium-power RF generator modules that provide high voltage output in the radio-frequency range. They are designed as part of an RF power delivery system for aestetic medicine and vacuum plasma applications.

Please note, these modules are not stand-alone solutions; for proper operation, they require external sources of high-voltage DC (HV DC) (for ex. PCA-series capacitor charger) and low voltage 24 V DC of appropriate power levels.

Output power varies from 300W (for 81.36 MHz) to 1500W depending on the model, and the output frequency is fixed (6.78, 13.56, 27.12, 40.68, 81.36 MHz or 0.5-4 MHz are available on request).
Modules are cooled with a built-in fan.

The average output power of a module can be regulated in two different ways:
– by varying the input DC voltage (the output power of the RF generator module increases with the input voltage)
– or by multi-kilohertz PWM (Pulse Width Modulation) of the output (set by an external controlling device with the Power control signal or via RS-485). The average output power in this case is linear with the duty cycle.

There is a power generation mode possibility when the output power is very stable during the time, monitored and adjusted by integrated PID controller.

RFGM modules have advanced measuring circuits. Forward power, reflected power, load impedance are continuously and precisely monitored.

Since the modules for aesthetic medicine are designed to be integrated into secondary circuits of medical RF systems, they do not need individual certificates of compliance to medical standards, although they fully comply with them. Therefore, they can be used in medical systems without any modifications, additional filtration, or additional means of protection. They can be certified by the user as part of a complete system.
