Abstract
An RF front end circuit has a common impedance matching network connected to an output terminal, a first power amplifier arranged to drive power to the output terminal through the common impedance matching network, a second power amplifier adapted to drive power to the output terminal through the common impedance matching network, a second impedance matching network, and a reference terminal at a reference voltage. The second impedance matching network has at least a first connection path to the reference terminal, a second connection path to the second power amplifier and a third connection path to the common impedance matching network. The second impedance matching network also includes a first impedance switch configured to open the first connection path responsive to the second power amplifier being put into an OFF state.
