Balun comprising two conversion circuits each constituted by first to third FBARs |
摘要 |
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. |

1. A balun, comprising:
two conversion units configured to control the phase of an input signal, the two conversion units each consisting of a first FBAR, a second FBAR, and a third FBAR located between the first FBAR and the second FBAR, the third FBAR being connected to a ground; and a first port connected between the two conversion units and which is configured to receive an unbalanced signal, a second port connected to a first conversion unit from among the two conversion units, and a third port connected to a second conversion unit from among the two conversion units, wherein the two conversion units are connected to each other in series. |
