The signal splitter for laboratory GNSS signal distribution

摘要

The paper presents a design of a four way signal splitter working in L frequency band, for standard GNSS (Global Navigation Satellite Systems) signals. These splitters are used when more than one receiver has to be connected to one signal source, like an antenna, a signal distribution socket or a test signal generator. The advantage of the solution is realization by a PCB structure, without need of any expensive or hard to find special components. The splitter is also integrated with a transformation from 75 Ω to 50 Ω. Then cheaper 75 Ω cable can be used for the signal distribution system. Final results from the splitter testing are also included in the paper.
