摘要： An amplification device includes a series combination of a driver stage, an output terminal matching network, and a secondary amplification stage. The driver stage includes a driver amplifier and an output matching network. The secondary amplification stage includes a parallel combination of an impedance transformation network and a main amplification stage. The main amplification stage includes a plurality of main amplification branches in parallel with each other, and an input matching network in series with the parallel combination. Each main amplification branch includes a main amplifier, and input and output impedance matching networks. A control circuit supplies activation signals to the main amplification branches to selectively turn them on and off. The device has no switches in the path of the signal that is amplified. In at least one operating mode, the control circuit turns on at least two of the main amplification branches at the same time.
