Abstract
A transmitter includes a transmitter circuit, a calibration circuit, and a transmitter signal strength indicator circuit. The transmitter circuit is coupled to a power node to receive a supply voltage and transmits an output signal via an antenna. The calibration circuit senses a current of the power node when the transmitter circuit operates in a first frequency band and operates in a second frequency band to generate a signal having different values and generates a calibration signal according to the signals having the different values. The transmitter signal strength indicator circuit detects power of the output signal to generate a first detection signal, and generate a second detection signal according to the calibration signal and the first detection signal. The transmitter circuit adjusts the power of the output signal to be target power according to the second detection signal.
