    摘要: The invention relates to an electronic device comprising an RF-LDMOS transistor (1) and a protection circuit (2) for the RF-LDMOS transistor. The protection circuit (2) comprises: i) an input terminal (Ni) coupled to a drain terminal (Drn) of the RF-LDMOS transistor (1); ii) a clipping node (Nc); iii) a clipping circuit (3) coupled to the clipping node (Nc) for substantially keeping the voltage on the clipping node (Nc) below a predefined reference voltage, wherein the predefined reference voltage is designed to be larger than the operation voltage on the drain terminal (Drn) and lower than a trigger voltage of a parasitic bipolar transistor that is inherently present in the RF-LDMOS transistor; iv) a capacitance (Ct) coupled between the clipping node (Nc) and a further reference voltage terminal (Gnd), and v) a rectifying element (D1, D2) connected with its anode terminal to the input terminal (Ni) and with its cathode terminal to the clipping node (Nc). The invention provides an RF-LDMOS transistor having an improved RF ruggedness, while not, or at least to a much lesser extent, compromising the RF performance of the RF-LDMOS transistor.
