Abstract
A DC blocking device using impedance matching is disclosed. The disclosed DC blocking device comprises: a first strip line configured to receive a signal and including a first line section and a first joining section joined to a part where a signal is received; and a second strip line separated from the first strip line at a designated distance and including a second line section and a second joining section for joining an output signal, where coupling occurs from the first strip line to the second strip line, the first strip line and the second strip line each have at least one bending section, and the first line section and the second line section have smaller line widths than the first joining section and the second joining section. The disclosed DC blocking device has the advantage of minimizing spatial constraints when it is installed in a mobile communication apparatus, and of achieving proper coupling even if the length of the part of the DC blocking device where coupling occurs is reduced.
