I have a coaxial cable whose length is $$L=10m$$, working at $$f=1GHz$$ frequency and i need to determine it's attenuation coefficient (if that is correct term), however i cannot find any relationship between these three values anywhere on the internet so i would appreciate if someone could help me! Thanks in advance!
the data sheet of your table should provide constants for it, the formula I see often is
whoever makes your cable sometimes provides their constants in the documentation so you can get an estimate. If there are none, find a similar cable an estimate with a maker that provides them. Usually they end up giving you a value per unit of length.
I really do not know how to write equations properly on here.
