Abstract: The present invention relates to a method for automatically regulating the HF output power of a high frequency amplifier wherein a regulating voltage is utilized to produce a control voltage or a control current for controlling the gain of the amplifier, a first voltage which depends on the HF output power is derived from the supply voltage and/or from the supply current of the current supply device providing the power required to generate the HF power; the regulating voltage is formed of two components, with the first component being generated from the first voltage and a first reference voltage, and with the second component being generated from a second voltage which depends on the control voltage or on the control current generated by the control voltage and from a second reference voltage; and that for high HF power essentially only the first regulating component is active and for low and medium power, whose range approximately covers the linear operating range of the amplifier, essentially only the seco
