2023年2月18日 · Path resistance is a combination of relay contact resistance and trace resistance. Contact resistance typically remains low for the life of a relay. At the end of relay life, the contact resistance rises rapidly above 1.0 Ω. Refer to the following figures for typical insertion loss, typical VSWR, and typical isolation. Figure 1.
