Patent ID: 8744378

Claim:
An apparatus comprising: a first driver that is configured to receive a first set of complementary radio frequency (RF) signals; a second driver that is configured to receive a second set of complementary RF signals; a first restoration circuit that is coupled to the first driver; a bridge circuit that is coupled to the first and second restoration circuits; a second restoration circuit that is coupled to the second driver; and an output circuit that is coupled to the first and second restoration circuits, wherein the first restoration circuit, the second restoration circuit, and the bridge circuit provide a common mode impedance and a differential impedance, wherein the common mode impedance is lower than the differential impedance, a first cancellation circuit that is coupled to the first driver; and a second cancellation circuit that is coupled to the second driver, wherein the first and second cancellation circuits increase peak efficiency wherein the first and second restoration circuits further comprise first and second inductor-capacitor (LC) circuits.
