摘要： 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.

摘要： Examples of a capacitive-coupled bandpass filter include a plurality of coupling capacitors connected in series along a signal path extending between an input contact and an output contact, a first harmonic suppression notch circuit configured to provide a first harmonic suppression notch in a frequency response of the capacitive-coupled bandpass filter, and a second harmonic suppression notch circuit configured to provide a second harmonic suppression notch in the frequency response of the capacitive-coupled bandpass filter. The first harmonic suppression notch circuit includes a first pair of series L/C resonators connected in shunt between the signal path and a reference potential, and the second harmonic suppression notch circuit includes a second pair of series L/C resonators connected in shunt between the signal path and the reference potential.

摘要： A front-end module of a wireless device can replace a passive duplexer with an active duplexer that uses metamaterial matching circuits. The active duplexer can be formed from a power amplifier circuit and a low noise amplifier circuit that each include a metamaterial matching circuit. The combination of a power amplifier circuit and a low noise amplifier circuit that each utilize metamaterials to form the associated matching circuit can provide the functionality of a duplexer without including the additional circuitry of a stand-alone or passive duplexer. Thus, in certain cases, the front-end module can provide duplexer functionality without including a separate duplexer. Advantageously, in certain cases, the size of the front-end module can be reduced by eliminating the passive duplexer. Further, the loss introduced into the signal path by the passive duplexer is eliminated improving the performance of the communication system that includes the active duplexer.

摘要： A power amplifier module can be formed that includes metamaterial matching circuits. This power amplifier module can be included as part of a front-end module of a wireless device. The front-end module can replace a passive duplexer with an active duplexer that uses the power amplifier module in combination with a low noise amplifier circuit that can include a metamaterial matching circuit. The combination of PA and LNA circuits that utilize metamaterials can provide the functionality of a duplexer without including a stand-alone or passive duplexer. Thus, in certain cases, the front-end module can provide duplexer functionality without including a separate duplexer. Advantageously, in certain cases, the size of the front-end module can be reduced by eliminating the passive duplexer. Further, the loss introduced into the signal path by the passive duplexer is eliminated improving the performance of the communication system that includes the active duplexer.
