摘要：
A balun transformer includes a first conductive pattern having one end provided as an input/output port of an unbalanced signal, a second conductive pattern electromagnetically coupled to the first conductive pattern and having both ends provided as input/output ports of a balanced signal, and a first variable capacitor connected between a ground part and a middle part of an electrical length of the second conductive pattern.
