What shows in the figure is the RF power control system circuit formed by single-chip RF power measurement system MAX2015. The set point voltage USET provided by D / A converter (DAC) is linked to the SET side of MAX2015. RF signals emitted by the antenna pass through the coupler to the input of MAX2015. MAX2015's output voltage Uo acts as input signal of the variable gain amplifier and is used to control the transmission power.
