A radiofrequency (RF) power regulator includes a forward RF power detection circuit to detect forward RF power supplied by an RF transmitter circuit to an RF transmitting antenna. An RF power sampler is coupled to the forward RF power detector circuit and provides RF power samples of the supplied forward RF power. Multiple filters are coupled to receive the RF power samples. Each filter differently filters the received forward power samples to apply a different average power period. Each filter activates an RF power adjustment trigger signal while a time-averaged forward RF power supplied to the RF transmitting antenna satisfies a forward RF power adjustment condition for the average power period of the filter. Forward RF power adjustment logic is coupled to filters and operable to adjust the forward RF power supplied by the RF transmitter circuit to the RF transmitting antenna based on the RF power adjustment trigger signal.
