Abstract: A frequency multiplier with a series resonant reflector is provided to improve the output power and to reduce the size, by reflecting a signal regardless of high and low frequency with the series resonant reflector. In a frequency multiplier with a series resonant reflector(250), electric sources(200,210) provide the electric power to a frequency multiplying unit(240). An input DC blocking unit(220) removes the DC(Direct Current) component of signal having an inputted reference frequency component. An input matching unit(230) matches a signal having the reference frequency component. The frequency multiplying unit(240) receives the signal having the reference frequency component matched at the input matching unit(230), outputs the signal having reference frequency component and a signal having the harmonic component and amplifies the output by using the signal having the reference frequency component reflected from the series resonant reflector(250). The series resonant reflector(250) reflects the signal having the reference frequency component outputted from the frequency multiplying unit(240) with the frequency multiplying unit(240). An output matching unit(260) selects a signal having a predetermined first multiplying component among the signal having the harmonics component outputted from the frequency multiplying unit(240). An output DC blocking unit(270) removes the DC component of signal having a predetermined component selected at the output matching unit(260).
