Disclosed is an amplifier circuit with cross wiring of direct-current signals and microwave signals. The circuit includes a circuit network unit formed of a direct-current feeding circuit and a microwave power signal circuit. The direct-current feeding circuit starts from a high-electron-mobility transistor (HEMT) drain power-up bonding point (211), and is connected to a feeding end of a tail-level HEMT transistor core (250) via a corresponding line after being connected to a first Metal-Insulator-Metal (MIM) capacitor (221) in parallel, and connected to a first micro-strip inductor (222) and symmetrical branch micro-strips (223) in series, the branch micro-strips (223) being connected to one of electrodes of second MIM capacitors (231, 234) in series. The microwave power signal circuit starts from a signal end of the tail-level HEMT transistor core (250), is combined into two paths by a corresponding line, the two paths being respectively connected to two third MIM capacitors (241, 242) in parallel, being re
