TUNABLE LOADLINE

摘要

A tunable loadline is disclosed. In an exemplary embodiment, an apparatus includes an amplifier configured to output an amplified signal having a selected power level and a first impedance network coupled to receive the amplified signal at an input terminal and generate a first output signal having a first power level at a first output terminal. The first impedance network being configured to load the amplified signal to convert the selected power level to the first power level. The apparatus also includes a second impedance network configured to selectively receive the first output signal and generate a second output signal having a second power level at a second output terminal. The second impedance network being configured to combine with the first impedance network to load the amplified signal to convert the selected power level to the second power level.
