摘要： Provided are a resonator and a filter performing a filtering operation by using the resonator. The filter includes a first resonation unit connected in series to an input terminal and having a first resonant frequency, a filtering unit connected in series to the first resonation unit to filter a signal inputted through the input terminal, a second resonation unit connected in series between the filtering unit and an output terminal and having a second resonant frequency, a first zero-order resonation unit connected in parallel to a connection terminal between the input terminal and the first resonation unit and having a first zero-order resonant frequency equal to the first resonant frequency, and a second zero-order resonation unit connected in parallel to a connection terminal between the output terminal and the second resonation unit and having a second zero-order resonant frequency equal to the second resonant frequency.
