A symbol power tracking amplification system including: a modem to generate data and symbol tracking signals; a symbol tracking modulator including a control circuit, first and second voltage supply circuits and a switch circuit, the control circuit generates first and second voltage level control signals in response to the symbol tracking signal, the first voltage supply circuit generates a first output voltage in response to the first voltage level control signal, the second voltage supply circuit generates a second output voltage in response to the second voltage level control signal and the switch circuit outputs the first or second output voltages as a supply voltage in response to a switch control signal; an RF block to generate an RF signal based on the data signal from the modem; and a power amplifier to adjust a power level of the RF signal based on the supply voltage.
