Abstract: The effects of the material parameters of circuit substrate and micro-assembly process parameters of the phase-shifting module on the amplitude-phase characteristics are simulated and analyzed. The dielectric constant of the substrate has a significant impact on the phase of modules, and has a small impact on the amplitude of signals. Loss tangent and surface roughness have an important effect on the transmission loss, and have a negligible effect on the phase. The loop height and the distance of gold wires have great impacts on the amplitude and phase of signals, respectively. The consistency of the substrate material parameters and micro-assembly process parameters should be improved to guide the amplitude-phase consistency of microwave modules. Meanwhile, in order to improve the performance of microwave modules, the loop height of bonding wires should be less than 0.20 mm, the distance of gold wires should be less than 0.30 mm.
