The invention discloses a millimeter wave frequency multiplier circuit capable of realizing fundamental wave offset. The millimeter wave frequency multiplier circuit comprises an input port, a first capacitor, a transformer, a second capacitor, a first resistor, a first field effect transistor, a second resistor, a second field effect transistor and an output port. According to the millimeter wave frequency multiplier circuit structure, two paths of fundamental wave signals with opposite phases are superposed to realize fundamental wave offset, so that the fundamental wave output is inhibited, the output proportion of double frequency multiplication and triple frequency multiplication is improved, and the frequency multiplication function is effectively realized. According to the millimeter wave frequency multiplier circuit structure, output of double frequency and triple frequency can be achieved at the same time, the amplitude of output of double frequency and triple frequency can be effectively controlled through the working states of the two circuits and the field effect transistor, and other harmonic waves are restrained. The millimeter wave frequency multiplier is simple in circuit structure, convenient to control and adjust output, few in components, easy to implement and capable of effectively reducing cost.
