Abstract
An RF PA and an RF PA protection circuit are disclosed according to one embodiment of the present disclosure. The RF PA includes an RF PA bias circuit and an RF PA transistor element. The RF PA transistor element has a first current terminal and a control terminal. The RF PA protection circuit is coupled between the RF PA bias circuit and the first current terminal. The RF PA protection circuit reduces a current through the first current terminal using the RF PA bias circuit when a magnitude of a voltage at the first current terminal exceeds a protection threshold.
