ABSTRACT:
An amplifier includes: a substrate; first to fourth amplifying units arranged on the substrate and each having first and second terminals, and each amplifying first and second signals to generate first and second amplified signals; a first inductive line arranged on the substrate, connecting the first terminal of the first amplifying unit and the first terminal of the second amplifying unit, and having a linear portion and a bending portion; a second inductive line arranged on the substrate, connecting the second terminal of the second amplifying unit and the first terminal of the third amplifying unit, and having a linear portion and a bending portion; a third inductive line arranged on the substrate, connecting the second terminal of the third amplifying unit and the first terminal of the fourth amplifying unit, and having a linear portion and a bending portion; a fourth inductive line arranged on the substrate, connecting the second terminal of the fourth amplifying unit and the second terminal of the first amplifying unit, and having a linear portion and a bending portion; and a fifth inductive line which establishes magnetic field coupling with the first to fourth inductive lines, and has third and fourth terminals, combines the plurality of the first amplified signals amplified to output the first combined signal from the third terminal, and combines the plurality of the second amplified signals to output the second combined signal from the fourth terminal.
