Description

The LDCBS1X2 GPS Splitter is a one input, two output device based on the Wilkinson splitter design. The frequency response covers the GPS L1 & L2 bands with excellent gain flatness. In the normal configuration, one of the splitter RF outputs (J1) passes DC from the connected GPS receiver through the splitter to the antenna. The other RF output (J2) is DC loaded with a 200Ω resistor to block the DC voltage and to simulate the antenna current draw to prevent false antenna fault detection.
