16-channel GPS antenna splitter
BGT-KOH: Desktop Enclosure
In several use cases there is a need for providing a GPS reference signal to a variety of device with built-in receivers. Running separate Antenna cables to each of those GPS receivers is often difficult and cumbersome. This includes, for example lab setups where many cellular base stations with GPS clock reference input are operated lab setups wit a variety of measurement devices that utilized GPS disciplined reference clocks in-building distribution of GPS RF signals The sysmocom 16-channel GPS antenna RF splitter is the ideal solution for such setups. Its unparalleled number of 16 receiver-side RF ports allow for a large density of GPS receivers. The GPS RF signal of a single GPS antenna (which can optionally be phantom powered by the splitter) is filtered, amplified, filtered again and then split (in two stages of 1:4 dividers) across 16 RF outputs. Each output features an integrated DC-block and a dedicated LED to indicate if phantom voltage is supplied by the attached receiver or not. Supported biasing voltages on the output side are in the range of 3 .. 12V DC.The product is available in two form-factors a stand-alone extruded aluminum desktop enclosure - useful for portable operation on a lab desk as a module for a 3U component carrier - a perfect fit for larger rack-mounted lab installation or in-building GPS RF signal distribution Further LinksProduct HomepageData Sheet
