Now I need to transfer 13.56MHz sinewave power from Class-E Power Amplifier to 50 Ohm Dummy Load through Coaxal Cable.
I studied about Coaxial Cable and I found something don't understand why .
I study about Coaxial Cable has it own impedance (normally 50 Ohm )
Is it represent It's own resistance of 50 Ohm at certain frequency range?
if it is true , A transmission line has resister on it , is it cause power loss on transmission line itself when current pass through it? why don't use near 0 Ohm cable?
If I make Cable by myself, can I Increase or decrease length for vary the resistance in Coaxial Cable?
I go study wiki but I really don't understand the reality about Cable impedance.
