Abstract:
1. A protection module for protecting a RF-amplifier against overvoltage due to load impedance mismatch when said RF-amplifier is connected to a load RF-element, said protection module having an input terminal able to connect to a node belonging to a RF-signal transmission link from the RF-amplifier to the load RF-element, and the protection module also having a reference terminal able to connect to a reference terminal of the RF-amplifier, said protection module comprising: a branch connecting the input terminal of the protection module to an intermediate node, said branch comprising at least one diode-like operating component; a first resistance and a first capacitor connected in parallel to one another between the intermediate node and the reference terminal of the protection module; and an inductor with a first terminal of said inductor connected to the input terminal of the protection module, wherein: the branch further comprises a second resistance connected in series with respect to the at least one diode-like operating component between the input terminal and the intermediate node of the protection module; and a second terminal of the inductor is connected to the intermediate node.
