A method, system, and apparatus of a DC current based on chip RF power detection scheme for a power amplifier are disclosed. In one embodiment, a method includes generating a scaled current from an other current associated with power amplifier, transforming the scaled current (e.g., the scaled current may be scaled to the other current value) into a digital signal and using the digital signal to set a radio frequency power value of an antenna of the antenna module. The method may include transforming the scaled current into a voltage signal. The method may also include transforming the voltage signal into the digital signal. The method may also include generating a current mirror from a low dropout regulator.
