Abstract: A broadband balun capable of improving integration by reducing the number of unit device and a manufacturing method thereof are provided to ideally maintain strength of a signal and a phase difference between balanced terminals by using a coupling of a resonator. A broadband balun comprises a first inductor(L1), a second inductor(L2), and a third inductor(L3). The first inductor is connected to an unbalanced terminal(P1). The second inductor and the third inductor are connected to balanced terminals(P2, P3). A direction of the first inductor is opposite direction of the second inductor, and is identical to direction of the third inductor. The first inductor, the second inductor, and the third inductor form a magnetic coupling. The balun is manufactured by a MMIC(Monolithic Microwave Integrated Circuit) technology or a LTCC(Low Temperature Co-fired Ceramic) technology.

Abstract: PURPOSE: A vibration energy collecting device based on an electromagnetic force is provided to implement an environment-friendly alternative energy source by removing harmful byproducts in a generation process. CONSTITUTION: A magnet unit(13) moves according to an external vibration. A buffer unit(11) supports the magnet unit. The buffer unit applies energy from the magnetic unit by transmitting vibrations. A coil unit is spirally wound around the magnet unit. A support unit maintains a constant distance between the coil unit and the magnet unit in a non-vibration state. The support unit supports the mutual combination between the coil unit and the magnet unit and protects the buffer unit and the coil unit from the outside. The magnet unit reciprocates in a spiral axis direction of the coil unit according to the surrounding vibrations. The magnet unit generates an electromotive force on both sides of the coil by using the variation of the magnetic field due to a relative position change.
