GPS Active Splitters

For large manufacturing facilities, Symmetricom Active Splitters can provide as many GPS-L1 (1575.42 MHz) signals as your manufacturing floor requires. With built-in amplification to overcome splitter losses, the Active Splitters can be conveniently cascaded without adding separate amplifiers and bias-tees between splitters.

High Isolation Eliminates Receiver Interactions
Symmetricom GPS Active Splitters have the essential port-to-port isolation required to eliminate interaction between multiple GPS receivers. Without such isolation, local oscillator (LO) leakage from one GPS receiver can prevent other receivers from acquiring time and position signals and maintaining lock. In wireless base station applications, poor isolation can disable cell sites. In GPS manufacturing tests, poor isolation causes repeatability problems which can reduce yields and cause false rework. Symmetricom Active Splitters have a minimum of 40 dB isolation at common GPS LO frequencies between every combination of output ports. Extensive field testing by GPS and cellular base station manufacturers has demonstrated suitability for use and the long-term dependability of Symmetricom GPS L1 Active Splitters.

Convenient DC Power Simplifies Your Installation
Power is conveniently obtained from the GPS receiver(s) connected to the amplifier. This eliminates the need for a separate dc power supply and wiring. DC power applied to the splitter is also passed on for use by an active antenna, further simplifying your installation.

Four Active Splitters
The 58535A (2 outputs), 58536A (4 outputs), and 090-58537-01 (4 outputs) obtain power from a GPS receiver connected to any port. The 58517A (8 outputs) receives power from the GPS receiver connected to port 1, and has an optional external DC connection if needed.
