Product Description
The LDCBS1X4 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 outputs (J2, J3, and J4) are DC loaded with a 200Ω resistor to simulate antenna current draw for receivers on those ports.
