摘要： A multi-mode multi-band power amplifier (PA) module is described. In an exemplary design, the PA module includes multiple power amplifiers, multiple matching circuits, and a set of switches. Each power amplifier provides power amplification for its input signal when selected. Each matching circuit provides impedance matching and filtering for its power amplifier and provides a respective output signal. The switches configure the power amplifiers to support multiple modes, with each mode being for a particular radio technology. Each power amplifier supports at least two modes. The PA module may further include a driver amplifier and an additional matching circuit. The driver amplifier amplifies an input signal and provides an amplified signal to the power amplifiers. The additional matching circuit combines the outputs of other matching circuits and provides an output signal with higher output power. The driver amplifier and the power amplifiers can support multiple output power levels.

摘要： An amplifier module with multiple operating modes is described. In an exemplary design, the amplifier module includes an amplifier (e.g., a power amplifier), a switch, and an output circuit. The amplifier receives and amplifies an input signal and provides an amplified signal in a first mode. The switch is coupled to the output of the amplifier and bypasses the amplifier and provides a bypass signal in a second mode. The output circuit is coupled to the amplifier and the switch. The output circuit performs output impedance matching for the amplifier in the first mode. The output circuit also (i) receives the amplified signal and provides an output signal in the first mode and (ii) receives the bypass signal and provides the output signal in the second mode. The amplifier is enabled in the first mode and disabled in the second mode.

摘要： Techniques for monitoring and controlling bias current of amplifiers are described. In an exemplary design, an apparatus may include an amplifier and a bias circuit. The amplifier may include at least one transistor coupled to an inductor. The bias circuit may generate at least one bias voltage for the at least one transistor in the amplifier to obtain a target bias current for the amplifier. The bias circuit may generate the at least one bias voltage based on a voltage across the inductor in the amplifier, or a current through a current mirror formed with one of the at least one transistor in the amplifier, or a gate-to-source voltage of one of the at least one transistor in the amplifier, or a voltage in a replica circuit replicating the amplifier, or a current applied to the amplifier with a switched mode power supply disabled.

摘要： An output circuit with integrated impedance matching, power combining, and filtering and suitable for use with power amplifiers and other circuits is described. In an exemplary design, an apparatus may include first and second circuits (e.g., power amplifiers) and an output circuit. The first circuit may provide a first single-ended signal and may have a first output impedance. The second circuit may provide a second single-ended signal and may have a second output impedance. The output circuit may include (i) first and second matching circuits that perform output impedance matching and filtering for the first and second circuits, (ii) a combiner (e.g., a summing node) that combines the first and second single-ended signals to obtain a combined single-ended signal, (iii) a third matching circuit that performs impedance matching and filtering for the combined single-ended signal, and (iv) switches to route the single-ended signals to different outputs.
