摘要： PROBLEM TO BE SOLVED: To provide an amplifier with high gain and high efficiency while the design thereof is simple.
SOLUTION: A high power Doherty RF amplifier utilizes multi-stage amplifier modules for both a main amplifier and a peak amplifier. In one embodiment of a two way two stage amplifier, the first stage of each amplifier module includes a signal pre-distortion function whereby distortion in both the first and second stages can be compensated. In one embodiment, a commercially available CREE PFM19030SM power module is used in both the main amplifier and the peak amplifier.

摘要： PROBLEM TO BE SOLVED: To provide an RF power amplifier amplifying an RF signal improved in efficiency over a wide range.
SOLUTION: The RF power amplifier amplifies RF signals over the power of a first range and includes a main amplifier having a lower power saturation level than a maximum power value of a wider range. A plurality of auxiliary amplifiers are connected with a main amplifier in parallel. Each auxiliary amplifier is biased so as to provide amplified output signals in order after the main amplifier approaches saturation. An input signal is supplied to the main amplifier and a plurality of auxiliary amplifiers through a signal splitter. The output receiving amplified output signal groups from the main amplifier and a plurality of auxiliary amplifiers includes a resistive load R/2. A distributed input signal is supplied to the main amplifier through a 90-degree transformer. The output of the auxiliary amplifier is supplied to an output load through the 90-degree transformer.

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. A plurality of 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 and the carrier amplifier delivers current to the load, which is one-half the current at maximum power when the amplifier is saturated. In one embodiment with the output having an impedance, Z, the carrier amplifier and each peak amplifier is connected to the output through an output-matching network presenting an output impedance of less than Z to each amplifier and with each output-matching network having selected phase length to reduce reactance of the output impedance.

摘要： The linearity of a transistor amplifier comprising a plurality of transistors operating parallel is improved by reducing the odd order transconductance derivatives of signals generated by the transistors. The transistors can be provided in groups with each group having a different bias voltage applied thereto or each group of transistors can have a different input signal applied thereto. The groups of transistors can have different physical parameters such as the width to length ratio of gates in field effect transistors and threshold voltages for the transistors.
