Abstract:
1. An amplifier module comprising: an integrated circuit device comprising a first amplifier circuit electrically connected to a first input terminal, the first amplifier circuit comprising x (x≧2) first amplifier branches electrically connected to the first input terminal; y (y≧2) first output terminals, each of the y first output terminals corresponding to a transmit frequency band; a first switching unit to electrically connect one or more of the first amplifier branches to one of the first output terminals; a multilayer substrate, the integrated circuit device and the first switching unit being mounted on the multilayer substrate; and a second input terminal, a second amplifier circuit, second output terminals, and a second switching unit, the second amplifier circuit comprising second amplifier branches, the second switching unit to electrically connect one or more of the second amplifier branches to one of the second output terminals; wherein the multilayer substrate comprises integrated passive matching elements that comprise parts of matching circuits; wherein each of the first amplifier branches is to deliver a different power level at a corresponding first amplifier branch outputs; wherein matching circuits are configured to match first amplifier branches to a load at the first output terminals; wherein matching circuits are configured to match second amplifier branches to a load at a second output terminal; and wherein the first input terminal is configured to receive a signal of a first frequency range and the second input terminal is configured to receive a signal of a second frequency range that is different from the first frequency range.
