Antenna power supply system: how does it work?

Hello,
i'm working now with the bias tee from Mini-circuits because my target is use the same cable (coaxial cable) for the signal and for the power supply like an antenna system.
I know that with high frequency is too simple devide the DC from the RF signal (with capacitor and inductor) but my problem is design a wideband amplifier (100MHz 1GHz) and use the same power supply method.
Can anyone give me some information or link to know well the problem and the solution?

thanks again
