Peak maximum current control for a wireless communication device. One example provides a radio including a radio frequency power amplifier (RFPA) and a current measuring circuit configured to sense a current provided to the RFPA. A comparator is connected to the current measuring circuit. The comparator is configured to compare a value indicative of the current provided to the RFPA to a threshold and provide an output indicative of the comparison. The radio includes a switching circuit configured to receive the output from the comparator and generate an amount of attenuation based on the output. A Cartesian feedback loop is configured to receive the amount of attenuation and control the output of the RFPA.
