Abstract:
A Radio Frequency (RF) amplifier structure, comprising:a first RF amplifier having an input and an output;a second RF amplifier having an input and an output;an RF output port; anda signal splitter/switching circuit coupled to the input of the first RF amplifier and the input of the second RF amplifier, the signal splitter/switching circuit comprising:at least one RF input port for receiving an RF signal; anda switching arrangement, coupled to the at least one RF input port and comprising at least one switch, to selectively switch in a portion of the signal splitter by opening the at least one switch in order to selectively couple the RF signal to the first RF amplifier to provide for tuning optimization of the first RE amplifier, wherein the at least one switch comprises a first switch and a second switch, and wherein the switching arrangement is capable of selectively switching out a portion of the signal splitter by opening the first switch and switching in the portion of the signal splitter by opening the second switch in order to selectively couple the RF signal to the first and second RF amplifiers to provide for tuning optimization of the first and second RF amplifies.
