The rf power stage is a power oscillator with a variable output voltage. The operation frequency is given by a built-in resonant circuit. The symmetry of the output voltage can be adjusted by a rotary capacitor at the front panel.
The rf output voltages of the module can be independently biased by different dc voltages. The required voltages can be connected to two BNC plug sockets at the front panel. To control the dc bias voltages, an external power supply is required. For this purpose, the following device was developed: Variable Power Supply/Power Amplifier 4×200 V.
The control electronics of the power stage is supplied by the power supply PSU +2V, +8V. The rf amplitude is controlled by regulating the supply voltage of the output transformers of the power stage. This voltage is provided by the module for controlling the rf amplitude (HV Control).
