The caple amplifier circuit composed of OPA660
Cable input signal VI is added to the pin 3 of OPA660 after passing 150Ω base resistor and 50Ω matched resistor, then it is output by pin 6 after being amplified by the internal OTA and +1 amplifier ( resistor RQ is not shown in figure in quiescent current ). Circuit gain G = RL / (RE + rE ) = +3.
