Abstract
Systems, methods, and devices relate to tunable baluns for multimode power amplification. For example, a variable-gain amplification system can include a power amplifier configured to provide an amplified signal and to selectively operate in at least a first gain mode and a second gain mode. The variable-gain amplification system can also include a tunable balun circuit configured to receive the amplified signal from the power amplifier and to provide an output signal. The tunable balun circuit can be configured to implement a first turn ratio for the first gain mode and a second turn ratio for the second gain mode.
