초록
A matching circuit in a communication apparatus may comprise a first inductor disposed at a primary side of a transformer; a second inductor disposed at a secondary side of the transformer; and an impedance element connected to the first inductor and the second inductor. Also, a first terminal of the first inductor may be connected to an input terminal of the transformer, a second terminal of the first inductor may be connected to a common node connected to a ground, a first terminal of the second inductor may be connected to an output terminal of the transformer, a second terminal of the second inductor may be connected to the common node, a first terminal of the impedance element may be connected to the common node, and a second terminal of the impedance element may be connected to the ground.
