Abstract:
A balun includes a first capacitor, a second capacitor, a first inductor, an unbalanced signal port, a first balanced signal port, and a second balanced signal port. The first capacitor and the second capacitor are electrically connected in series between the unbalanced signal port and the first balanced signal port. The first inductor is electrically connected in parallel to the first capacitor and the second capacitor electrically connected in series. A second signal path is electrically connected to a first signal path between the first capacitor and the second capacitor, and the second balanced signal port is electrically connected to the second signal path.
