Abstract
An amplifier comprises a carrier amplifier which performs signal amplification at all times, a peak amplifier which operates only at a time when the high electric power is outputted, a combiner which combines the output from the carrier amplifier and the peak amplifier, and a distributor which distributes an input signal to the carrier amplifier and the peak amplifier. The carrier amplifier and the peak amplifier are included in a single package transistor.
Claims20
An amplifier, comprising:
- a distributor which distributes input signals to two amplifiers;
- one or a plurality of linear amplifiers into which one signal from the distributor is input;
- one or a plurality of nonlinear amplifiers into which the other signal from the distributor is input;
- and
- a combiner that combines output signals from the linear amplifier and the nonlinear amplifier,
- wherein among a plurality of transistors included in a package, each of a predetermined number of the transistors comprises the linear amplifier, and each of the other transistors comprises the nonlinear amplifier, and
- wherein the package is directly connected to at least a gate electrode and a drain electrode.
