Disclosed is a balun including a film bulk acoustic resonator (FBAR). The balun may be implemented using the FBAR to fabricate a small sized balun. Also, the balun may be implemented using the FBAR, thereby reducing a difference in two outputs.

Provided is a bulk acoustic wave resonator (BAWR). The BAWR may include a bulk acoustic wave resonance unit and an anti-resonant frequency modifying unit to modify an anti-resonant frequency generated from the bulk acoustic wave resonance unit.

A balun includes an input line for receiving an unbalanced signal, an output line for receiving the unbalanced signal from the input line and outputting a balanced signal, and a ground. The input line and the output line are formed in the same layer, and the ground is formed in a different layer from the input line and the output line. The ground has an opening so as to generate a potential difference between the first output line and the second output line. The ground is electrically connected to the input line.
摘要:
A balun capable of a reduced whole size. The balun includes an input line receiving an unbalanced signal, an output line receiving the unbalanced signal from the input line and outputting a balanced signal, and a ground part. The input and output lines are formed on a layer, and the ground part is formed on a different layer from the layer. The ground part includes an opening and is electrically connected to the input line, and a portion of the ground part is removed to form the opening so that a potential difference occurs between first and second output lines. Thus, although a length of the output line is less than ¼ of an input wavelength λ, a difference between phases of first and second output signals can be about 180°. As a result, the whole size of the balun can be reduced.
