摘要： According to one embodiment, an amplifier circuit includes N (N>=3) transistors, two first branches and N−2 second branches. The N (N>=3) transistors are connected in parallel. The two first branches each include the transistor and a first transmission line which is connected to an output terminal of the transistor. The N−2 second branches each include the transistor and a second transmission line which is connected to the output terminal of the transistor. For each of the first branches, a sum between an electrical length of a parasitic component of the transistor and the electrical length of the first transmission line are odd multiples of approximately 90 degrees. For each of the second branches, the sum between the electrical length of the parasitic component of the transistor and the electrical length of the second transmission line are multiples of approximately 180 degrees.

摘要： An amplification apparatus as the embodiment of the present invention includes a switching amplifier and an adjuster. The switching amplifier is driven on the basis of a control signal and amplifies an input signal to be amplified to generate an amplified signal. The adjuster adjusts at least one of the signal to be amplified and the control signal before being input into the switching amplifier. In addition, the adjuster adjusts so that timing when the control signal turns from LOW to HIGH aligns with timing when the signal to be amplified turns from LOW to HIGH, or aligns with timing when the signal to be amplified turns from HIGH to LOW.

摘要： According to an embodiment, the modulated signal generating device modulates an input signal and generates an output signal. The modulated signal generating device includes a plurality of amplifiers, a combiner, a determining unit and a control signal generating unit. The plurality of amplifiers connects in parallel with one another and each configures to drive based on a control signal and to generate amplified signals. The combiner configures to combine the amplified signals and to obtain the output signal having a stepwise waveform. The determining unit configures to determine number of amplifiers to be driven based on a value of the input signal in a period shorter than a period of the input signal. The control signal generating unit configures to select zero or more amplifiers to be driven from among the amplifiers, based on the number of amplifiers determined by the determining unit, the value of the input signal, and a fluctuation in the value of the input signal, and to generate the control signal for driving the selected amplifier.

摘要： A modulated signal generating device that modulates an input signal and generates a modulated signal. The modulated signal generating device includes a first to p-th amplifier, where p=3 to N, and N represents an integer equal to or greater than three, a first to p-th control unit, a first to p−1-th filter, and a combiner. The first amplifier generates a first amplified signal based on a first control signal. The first control unit generates the first control signal based on a first component signal included in the input signal. The first filter eliminates harmonic component included in a first difference signal representing difference between the input signal and the first component signal, and generates a first filtered signal. The combiner combines the first to a p-th amplified signal to generate the modulated signal.
