DC resistance

The DC resistance of a coaxial cable actually has a significant influence on the transmittable power and the characteristic impedance of the cable. A high DC resistance leads to losses in the form of heat and reduces the efficiency of signal transmission. In addition, a high DC resistance can change the characteristic impedance of the cable, which can lead to impedance matching problems.

To minimise the negative effects of DC resistance, it is important to select suitable materials for the coaxial cable. Materials with low specific electrical conductivity, such as high-purity copper or aluminium, are often used to reduce DC resistance. In addition, special coatings or alloys can be used to further improve electrical conductivity and minimise losses in the cable.

By using materials with a low DC resistance, the transmittable power of the coaxial cable can be maximised and the characteristic impedance stabilised. This contributes to efficient and reliable signal transmission, especially in high-frequency applications where minimal losses and precise impedance matching are crucial.
