摘要： A radio frequency power amplifier (RF PA) apparatus includes a first RF PA, a second RF PA, and a controller. The first RF PA is configured to deliver RF power to a load over a first range of RF power levels. The second RF PA is configured to deliver RF power to the load over a second range of RF power levels greater than the first range of RF power levels. The controller controls whether the first RF PA is delivering RF power to the load or the second RF PA is delivering RF power to the load, and is further configured to coordinate and control handoffs between the first and second RF PAs by varying magnitudes of input RF voltages applied to the RF input ports of the first and second RF PAs or by varying magnitudes of input bias voltages applied to the RF input ports of the first and second RF PAs.

摘要： A scalable periphery tunable matching power amplifier is presented. Varying power levels can be accommodated by selectively activating or deactivating unit cells of which the scalable periphery tunable matching power amplifier is comprised. Tunable matching allows individual unit cells to see a constant output impedance, reducing need for transforming a low impedance up to a system impedance and attendant power loss. The scalable periphery tunable matching power amplifier can also be tuned for different operating conditions such as different frequencies of operation or different modes.
