Patent ID: 8896372

Claim:
An amplification apparatus for generating two constant amplitude signals from an input signal by vector decomposition and amplifying the two constant amplitude signals, the apparatus comprising: a first amplification section which amplifies a first signal obtained by the vector decomposition; a second amplification section which amplifies a second signal obtained by the vector decomposition; an impedance inverting circuit which inverts impedance of the second signal amplified by the second amplification section; and a combining circuit which corrects a phase of the first signal amplified by the first amplification section and a phase of the second signal whose impedance is inverted by the impedance inverting circuit and which combines and outputs the first signal and the second signal, the combining circuit being implemented via transmission lines with a tetragon configuration; the combining circuit including asymmetrical circuit elements or the asymmetrical circuit elements being inserted between the first amplification section or the second amplification section and the combining circuit.
