An integrated circuit in hybrid or MMIC technology, the integrated circuit comprising a reconfigurable power amplification device, wherein said device comprises, includes, between an input and an output, a first power channel and a second power channel, positioned in parallel with each other and independent of each other, and a switching means for dynamically selecting either one of the power channels in order to forward a power between the input and the output of the device, characterized in that the switching means includes an output coupler capable of operating in a coupling mode or in a combination mode, and a control circuit of the output coupler so as to have said output coupler operating either in said coupling mode, so that a power path passes through the second power channel, or in said combination mode so that a power path passes through the first power channel.
