Matching segment circuit to which radio frequency is applied and radio frequency integrated devices using the matching segment circuit

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.
