    摘要： A Bulk Acoustic Wave Resonator (BAWR), a method of manufacturing of the BAWR, and duplexer including the BAWR are provided. The BAWR may include a first substrate including a via hole formed in a predetermined area of a bottom surface of the first substrate. A first air cavity may be formed above the first substrate, and a first lamination resonating portion may be laminated above the first air cavity in sequence of a lower electrode, a piezoelectric layer, and an upper electrode. A second air cavity may be formed above the first substrate, and a second lamination resonating portion may be laminated above the second air cavity in sequence of the lower electrode, the piezoelectric layer, and the upper electrode. The first lamination resonating portion and the second lamination resonating portion may be connected via either the lower electrode or the upper electrode. A first electrode portion may include a third air cavity formed on a bottom surface of either the lower electrode or the upper electrode connecting between the first lamination resonating portion and the second lamination resonating portion.

    摘要： Provided are a matching segment circuit, to which a radio frequency (RF) is applied, and an RF integrated device using the matching segment circuit. The matching segment circuit to which an RF is applied may include an input end connected to a first RF device, a parallel segment having a first capacitor and a first inductor connected in parallel, a second inductor connected to the parallel segment in series, and an output end connected to a second RF device. The first capacitor, the first inductor, and the second inductor may be configured so that an impedance of the first RF device and an impedance of the second RF device may match.
