Abstract
Systems, methods, and devices relate to tunable circuits for multimode power amplification. For example, a variable-gain amplification system can include an 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 circuit configured to receive the amplified signal from the amplifier and to provide an output signal. The tunable 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.

A variable-gain amplification system comprising:
- an amplifier configured to provide an amplified signal and to selectively operate in at least a first gain mode and a second gain mode;
- and
- a tunable circuit configured to receive the amplified signal from the amplifier and to provide an output signal, the tunable circuit being configurable to a first turn ratio for the first gain mode and a second turn ratio for the second gain mode.
A radio-frequency module comprising:
- a packaging substrate;
- an amplifier disposed on the packaging substrate, the amplifier being configured to selectively operate in at least a first gain mode and a second gain mode;
- and
- a tunable circuit disposed on the packaging substrate, the tunable circuit being coupled to the amplifier and being configurable to a first turn ratio for the first gain mode and a second turn ratio for the second gain mode.
A radio-frequency device comprising:
- an amplifier configured to generate an amplified signal and to selectively operate in at least a first gain mode and a second gain mode;
- a tunable circuit coupled to the amplifier and configured to provide an output signal, the tunable circuit being configured to implement a first turn ratio for the first gain mode and a second turn ratio for the second gain mode;
- and
- a controller coupled to the tunable circuit and configured to provide a control signal to the tunable circuit to control a turn ratio state of the tunable circuit.
