Power amplifier (pa) with increased dynamics and efficiency

A power amplifier that operates at a high efficiency over a wide power range. In one embodiment, the power amplifier includes a first circuit having a first transistor including an input terminal for receiving an RF input, a first output terminal connected to ground, and a second output terminal connected to a first inductor connected in series with a capacitor and also connected to a voltage supply through a first controllable connector; a second circuit including a second transistor having an input terminal for receiving the radio frequency (RF) input, a first output terminal connected to ground, and a second output terminal connected to a second inductor connected in series with the capacitor and also connected to a voltage supply through a second controllable connector; and bias means for biasing the first transistor and the second transistor, wherein the first circuit is connected in parallel to the second circuit.
