摘要: The electronic device comprising a RF transistor (100) that is designed for a fundamental RF frequency and that is integrated with an electrostatic protection structure (250) with a further transistor (200). The transistors are suitably MOS transistors, with a gate, source and drain electrodes, and wherein the sources are coupled to a grounded substrate region. The drain region of the further transistor is coupled to the gate of the RF transistor (100), giving rise to a parasitic diode (300) between the drain region of the further transistor and the grounded substrate region under application of a certain input voltage. A filter (350) is present for filtering the fundamental RF frequency from the parasitic diode (300).
