Patent ID: 8466745

Claim:
A RF PA configured to amplify an RF signal between a source node RFIN and an output node RFOUT in a selectable plurality of frequency bands and wireless communication standards, the PA comprising: a) a driver stage power device configured as a first amplification stage; and b) a power stage power device configured as a last amplification stage; c) an input matching network in the front of the driver stage power device; d) an inter-stage matching network between the driver stage power device and the power stage power device; and e) an output matching network after a power stage power device, wherein the driver stage power device is fabricated over a SOI integrated circuit die and comprises a plurality of parallel cells, wherein the power stage power device is fabricated over a GaAs die and comprises a plurality of parallel cells, such that the RF PA is configured to operate in multi-bands and multi-modes, and wherein the input matching network, the inter-stage matching network, and at least a portion of the output matching network are fabricated over the SOI integrated circuit die and comprise a plurality of switches adapted to reconfigure the RF PA for different bands and modes.
