Abstract
According to at least one example of the disclosure, a power amplifier system is provided comprising an amplifying transistor configured to amplify a radio frequency signal, a bias circuit configured to provide a bias voltage to the amplifying transistor, and a clamp circuit for protecting the power amplifier system by absorbing a current flowing through the amplifying transistor when the clamp circuit is switched on. The clamp circuit is connected at a bias node between the bias circuit and the amplifying transistor and includes a clamp transistor and a clamp diode, the clamp diode having one end connected to a collector of the clamp transistor at the bias node and another end connected to a base of the clamp transistor.
