<p>The present invention relates to a multi-path variable matching circuit and a multi-path variable matching method using the same. To this end, the multi-path variable matching circuit according to an embodiment of the present invention is installed between an output end of a first device and an input end of a second device, thereby matching the output impedance of the first device with the input impedance of the second device, wherein the circuit connects a plurality of switch and impedance pairs to the output end and the input end and simultaneously controls the switching on/off of the plurality of switches, thereby maximizing an impedance matching coverage. Also, the multi-path variable matching circuit according to the present invention may control the switching on/off of switches based on frequency band information and adjust the capacitance of a variable capacitor based on channel information on a frequency band, thereby performing more exact impedance matching.</p> |
