GPS Source S18GT – 1×8 GPS Timing Reference Splitter


The S18GT GPS timing reference splitter from GPS Source has been specifically designed for the L band frequency. Built to eliminate the cost of multiple antennas and long cable runs in wireless installations, it makes it possible to use a single GPS referencing antenna and cable arrangement for multiple synchronized systems.



The S18GT 1 x 8 GPS timing reference splitter from GPS Source will support long-lasting, trouble free deployment in a small cell wireless and/or DAS environment. The device makes it possible to use a single GPS referencing antenna for synchronization systems, increasing capacity without increasing GPS antennas or cabling requirements.

Power is obtained from the GPS receiver(s) connected to the amplifier. There is no need for a separate DC power supply or wiring. DC power applied to the splitter is also passed on and utilized by an active antenna. It can obtain power on any of the four outputs from a GPS receiver connected to any port.

The S18GT features an antenna DC bias select circuit. This allows for the active antenna DC input to be applied to any or all RF outputs. With this feature, one DC voltage will be chosen to power the antenna while other inputs will be switched to DC loads. Designed for redundancy, if the selected DC bias input should fail, the DC bias will automatically switch to another DC input to ensure an uninterrupted supply to the active antenna.

The S18GT is an amplified device that is configured for 0 dB gain.


  • Delivers L band frequency signals to multiple GPS synchronization modules and receivers
  • Conveniently powered from a GPS receiver on any output port
  • Amplified to offset splitter losses
  • Optimum signal quality with low noise and high gain
  • High isolation will eliminate receiver interaction
