The invention relates to the field of radar communication, in particular to a millimeter wave circuit structure and a millimeter wave amplifier with the circuit structure. The millimeter wave circuitstructure comprises a triode, and the power supply branch of the triode is connected in series with an inductor or a microstrip line. A sunken filtering effect is formed by a bypass circuit formed byparallelly connecting capacitor to the ground after serially connecting the inductor to absorb out-of-band target frequency signal, and the inhibition degree between a working frequency band signal and the out-of-band target frequency band signal when the amplifier outputs is achieved. Signal inhibition of a specific frequency is achieved by adjusting the capacitance value of the capacitor. The device is simple in technology, simple in structure, easy for single-chip integration and small in occupied chip area. The millimeter wave power amplifier with the structure has the advantages of ensuring the output power capabi
