catv amplifier circuit

One option is to ask MAXIM-IC for samples of the MAX3654 ..
It is "47MHz to 870MHz Analog CATV Transimpedance Amplifier"

IanP proposed amplifier for optical fiber distribution. In the case of coaxial cable system you can use some MMIC like MAR-8. They can be found in old faulty satellite LNB.
