Key Features of High Frequency Performance
Characteristic impedance refers to the impedance of the cable when it is infinitely long. The characteristic impedance of a cable is a complex characteristic, which is determined by various physical parameters of the cable such as the values ​​of inductance, capacitance, and resistance, which in turn depend on the shape, concentricity, distance between conductors, and The material of the cable insulation. The characteristic impedance determines the quality of the transmission, and it is also the key to the problem of signal integrity. In addition, insertion loss, return loss, near-end crosstalk performance, combined with temperature vibration are also key performances and are important indicators of reliability.
