ComNav Technology, www.comnavtech.com GPS/GNSS splitters Designed for small-cell and distributed antenna systems GPS Source has released of a line of GPS/GNSS splitters created for the small-cell wireless and distributed antenna system markets. Specifically designed for the L-band frequency, they can eliminate the cost of multiple antennas and long cable runs in wireless installations. With four or eight outputs, the new line of splitters make it possible to use a single GPS referencing antenna and cable arrangement for multiple synchronized systems. The splitters include features such as DC bias select and amplification. GPS Source RF signal splitters typically operate in conjunction with an active GPS antenna; consequently, a GPS RF signal splitter must have provisions for managing the DC voltage to the active GPS antenna. The S14GT and S18GT splitters will power an external GPS antenna from any of the RF outputs. A “hunt-and-pick” circuit is used to select only one DC input for power should more than one source be connected. 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 power supply to the active antenna.
