摘要:
PIM characteristics of a planar printed circuit are evaluated experimentally by using 50 -microstrip line, of which causes are examined in terms of the physical and chemical conditions. Roughness on the treated surface of a microstrip line affects the PIM generation directly when the other conditions are fixed. However, the PIM has large dependence on the structural condition of the signal line such as line width and copper-clad thickness. Chemical composition of the copper foil is also investigated by using Auger electron spectroscopy, which suggests that some dissimilar materials such as Cr or Co are included in the copper foil generating high and unstable PIM.
