The invention provides an ultra-wideband high-harmonic suppression terahertz frequency multiplier. The frequency multiplier comprises an input port, an input end Marchand balun, a frequency multiplication unit circuit, an output end Marchand balun and an output port which are connected in sequence, wherein an isolation ring is arranged outside the frequency multiplication unit circuit, the input end Marchand balun performs equal-amplitude reverse-phase power division on an input signal, then frequency multiplication is performed through the frequency multiplication unit circuit, in-phase synthesis is performed through the output end Marchand balun, and a required broadband frequency multiplication signal is output through an output port. On the basis of the existing process capability, themulti-conductor coupling line Marchand balun with a tuning compensation unit is adopted to expand the working bandwidth and improve the harmonic suppression; and a tube core isolation ring structureis also adopted, so that t
