VARIABLE CAPACITOR, IMPEDANCE MATCHING DEVICE, MOBILE TERMINAL THEREOF AND METHOD FOR MATCHING IMPEDANCE

摘要

Disclosed is an impedance matching device. Variable devices of the impedance matching device installed in a mobile terminal, such as a portable terminal, are configured to have a MEMS structure. The MEMS structure and other components are integrated as one package, so the manufacturing cost is reduced and the manufacturing efficiency is improved.
