The MAX3660 evaluation kit (EV kit) is a factory-assembled PCB that provides an optical input with an electrical output. The optical circuit includes the photodiode bias circuitry, an op amp for feed-forward AGC operation, and a balun for single-ended 75Ω output. Through-hole pads are provided to attach a triplexer analog photodiode. It is important to select a photodiode with capacitance and inductance in the anode and cathode connections as symmetric as possible for optimum linearity.
