摘要： A power amplifier circuit (200) includes a power splitter (212, 214, 216) that splits an input signal (202) into a plurality of component input signals (218 a-d). At least two sets of transistor amplifiers (220, 230) are each coupled in parallel to the power splitter (212, 214, 216) to receive and amplify different ones of the component input signals (218 a-d) to generate amplified component output signals. The two transistor amplifiers of each set of transistor amplifiers (220, 230) are configured to turn on at different power levels of the input signal relative to each other. A combiner (240) is configured to receive and combine the amplified component output signals from the at least two sets of transistor amplifiers (220, 230) into an output signal (204). An integrated circuit package (210) encloses the power splitter (212, 214, 216), the at least two sets of transistor amplifiers (220, 230), and the combiner (240).

摘要： An RF power amplifier circuit for amplifying an RF signal over a broad range of power with improved efficiency includes a carrier amplifier for amplifying an RF signal over a first range of power and with a power saturation level below the maximum of the broad range of power is disclosed. One or more peak amplifiers are connected in parallel with the carrier amplifier with each of the peak amplifiers being biased to sequentially provide an amplified output signal after the carrier amplifier approaches saturation. The input signal is applied through a signal splitter to the carrier amplifier and the plurality of peak amplifiers, and an output for receiving amplified output signals from the carrier amplifier and the plurality of peak amplifiers includes a resistive load R/2. The split input signal is applied through a 90° transformer to the carrier amplifier, and the outputs of the peak amplifiers are applied through 90° transformers to a output load. When operating below saturation, the carrier amplifier delivers power to a load of 2R when the carrier amplifier delivers current to the load, which is one-half the current at maximum power and the amplifier is saturated. The signal splitter can split the input signal power equally among the carrier and one or more peak amplifiers, or the input signal can be split unequally with the carrier amplifier receiving less input power than each of the peak amplifiers and vice versa.
