Patent ID: 8774741

Claim:
A reconfigurable power amplifier comprising: a first transformation network including first and second inputs and an output; a second transformation network including third and fourth inputs and an output; wherein said first and second transformation networks are coupled together to drive a load; a first radio frequency (RF) amplifier coupled to the first and second inputs of the first transformation network; a second RF amplifier coupled to the third and fourth inputs of the second transformation network, wherein in a first mode of operation the first and second RF amplifiers contribute RF power to the load; a first circuit to disable the first RF amplifier so that it does not contribute RF power to the load in a reconfigured mode of operation; and a second circuit to couple said first and second inputs of the first transformation network together in the reconfigured mode of operation; wherein a load impedance at the third and fourth inputs of the second transformation network is different between the first mode of operation and the reconfigured mode of operation.
