4 Way GPS Splitter

Eliminate the cost of multiple antennas and long cable runs in your wireless base stations, Designed to meet the demanding, high reliability requirements of the wireless infrastructure market. The GEMS GS14i IS a high performance GPS signal splitter that can be configured to monitor the GPS antenna current , providing and alarm indication if the antenna is not operating to spec. The GS14i also features an optional antenna DC bias “Pick-&Choose” circuit which allows for active antenna DC input to be applied to any or all of the RF outputs, With this option ,one DC voltage will be chosen to power the antenna while the other input will be switched to DC loads, if the selected DC bias input should fail, the DC bias will be automatically switched to another DC input so as to ensure an uninterrupted supply to the active antenna. The GS14i man be configured as a passive or an active device, giving the network engineer the flexibility to specify the device gain and port-to-port isolation, The GS14i may also be ordered with surge protection on
all five ports and in a sealed housing sufficient for many years of Operation in external environments.

 [ Operation Description]

• Antenna DC Bias Select

       The GS14i splitter requires that a DC voltage be applied to one or more of the RF output ports by ways of the RF connector center conductor.If DC voltages are applied to more than one of the RF output ports,the GS14i pick-&-chose circuit will choose one of these DC input to power the active circuitry of the GS14i and will also pass this DC voltage through the splitter to the center conductor of the RF input port.The DC voltage available on the RF input port can then be used to power the application’s active antenna.The DC voltages applied to the RF outputs that are not chosen by the pick-&-choose circuitry will be automatically switched through an RF choke to 200Ohm DC loads. The DC voltages may be applied to any or alll of the RF outputs; however,the pick-&-choose circuit will always select the DC voltage ont the lowest numbered RF port that has a DC voltage applied to power the GS14i and the application’s antenna. If the choosen DC input were to be removed or fail,the pick-$-choosen circuit will automatically switch to the next higher mumbered RF port to which a DC voltage is applied.

• Antenna Monitor and Alarm

           The GS14iI includes  option to monitor the status of the application’s active antenna and to provide an alarm indication if the antenna’s current is not within a specified range.The default current window for the GS14i is 10mA to 150mA(e.g. below 10mA indicates an open circuit,above 150mA indicates a short circuit);however,for large volume orders,the antenna current window may be specified to meet the custmer’s specifiec requirements.   

• Amplifer and Splitter

            The GS14i has the option to be ordered as either a passive devide,of to be ordered with amplification.If the amplified option is chosen,additional options are available for specifying the amplifier gain and the poer-to-port isolatin(see Hi Iso.option in eletrical specifications).Amplified versions of the GS14i that also include the
High Isolation option do not require 50Ohm termination on unuesd ports in order for the splitter to peratte
properly.Passive versions or Amplified versions without the High solation option always require 50 Ohm
terminations on unused ports for proper operation.
