The NLDCBS1212 is a passive, networked GPS splitter with one input and two outputs and is based on the Wilkinson splitter design. The frequency response covers the entire GPS L-band (GNSS) frequencies with excellent gain flatness. In the standard configuration without external power, RF output (J1) passes DC from the connected GPS receiver, through the splitter and onto the antenna, while the other RF outputs remain DC blocked. When optional external power is applied, the DC output voltage on all RF outputs become user selectable. Each DC blocked output is loaded with a 200Ω resistor to simulate the antenna current draw to prevent false antenna alarm faults.
