摘要： An impedance matching circuit with at least one tunable notch filter for a power amplifier is disclosed. The power amplifier amplifies an input radio frequency (RF) signal and provides an amplified RF signal. The impedance matching circuit performs output impedance matching for the power amplifier and includes at least one tunable notch filter. Each tunable notch filter has a notch that can be varied in frequency to provide better attenuation of an undesired signal. The at least one tunable notch filter attenuates at least one undesired signal in the amplified RF signal. The at least one tunable notch filter may include (i) a first tunable notch filter to attenuate a first undesired signal at a second harmonic of the amplified RF signal and/or (ii) a second tunable notch filter to attenuate a second undesired signal at a third harmonic of the amplified RF signal.

摘要： Exemplary embodiments are directed to a transmitter with a power amplifier and a switched output matching circuit implementing a plurality of output paths for a plurality of operating modes is described. The power amplifier receives an input RF signal and provides an amplified RF signal. An output matching network performs impedance transformation from low impedance at the power amplifier output to higher impedance at the matching network output. The plurality of output paths are coupled to the output matching network. Each output path provides a different target output impedance for the power amplifier and routes the amplified RF signal from the power amplifier to an antenna when that output path is selected. Each output path may include a matching network coupled in series with a switch. The matching network provides the target output impedance for the power amplifier when the output path is selected. The switch couples or decouples the output path to/from the power amplifier.

摘要： A wireless device with power combining power amplifiers to support transmission on multiple antennas is disclosed. The power amplifiers may be operated together to obtain higher output power or separately to support transmission on multiple antennas. In an exemplary design, an apparatus includes first and second power amplifiers. The first power amplifier amplifies a first input signal and provides a first output signal for a first antenna in a first operating mode (e.g., a MIMO mode or a transmit diversity mode). The second power amplifier amplifies the first input signal or a second input signal and provides a second output signal for a second antenna in the first operating mode. The first and second power amplifiers are power combined in a second operating mode to provide a third output signal, which has a higher maximum output power than the first or second output signal.
