The invention relates to a configurable radio-frequency power amplifier and a radio-frequency transmitting front-end module with the same. The configurable radio-frequency power amplifier comprises a configurable radio-frequency power amplifier tube core (201) and a configurable output impedance matching network (202); the output end of the configurable radio-frequency power amplifier tube core (201) is connected with the configurable output impedance matching network (202); the configurable output impedance matching network (202) is provided with a plurality of impedance circuits comprising inductors and capacitors; and the configurable output impedance matching network also comprises a radio-frequency switch which controls switch-on or switch-off of each impedance circuit. The configurable radio-frequency power amplifier reduces the number of independent units of a multi-power mode radio-frequency front end and integrates two chips in a single module so that the area, occupied by the multi-power mode radio-frequency transmitting front-end module, of a circuit board of a mobile terminal is reduced, and meanwhile, the manufacturing cost of the mobile terminal is reduced.
