摘要： In accordance with a representative embodiment, an impedance matching circuit for use at an output stage of a power amplifier is disclosed. The impedance matching circuit comprises: an input port for receiving a frequency band signal; and a plurality of paths, each path being allocated with a principal band signal to be transmitted therethrough and including a path on-off network and a fixed-value impedance matching network. Depending on a type of the received frequency band signal, the path on-off network is configured to activate a selected one of the plurality of paths by rendering an input impedance of the selected path to have a lower absolute magnitude so that the signal is transmitted therethrough, and to deactivate the remaining paths of the plurality of paths by rendering the input impedance thereof to have a higher absolute magnitude so that the signal is not transmitted therethrough. The fixed-value impedance matching network matches a load impedance of the output port of each path to the input impedance thereof, thereby rendering the input impedance thereof to have a prescribed reference value with respect to the principal band signal when said path is activated by the path on-off network.

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.
