This paper introduces a method for designing a low-noise amplifier. Firstly, the main technical and performance indicators of the low-noise amplifier are described. Then, Agilent’s ATF-54143 is used to design the circuit based on the indicators of the low-noise amplifier. The circuit design and PCB board design of the low noise amplifier are completed. In the design, the influence of the PCB board on the amplifier is fully considered, and the full wave simulation data is imported into the circuit simulation for co-simulation. The final result indicates that the designed low noise amplifier Fully meet the expectations of the initial design.
