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.

Embodiments of circuits, devices, and methods for a power detection arrangement are disclosed. The power detection arrangement may have a coupler coupled with, and in between, a switch and an output to couple a signal to a detector. The power detection arrangement may include a harmonic suppressor coupled with, and in between, the coupler and the detector to reduce an amount of harmonic signals transmitted back to the coupler. Other embodiments may be described and claimed.
