    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 GPS/GNSS splitters make it possible to use a single GPS referencing antenna and cable arrangement for multiple synchronized systems. The splitters are available at a low price point and include features such as DC bias select and amplification.

    GPS Source RF signal splitters typically operate in conjunction with an active GPS antenna (a GPS antenna that includes an integrated low noise amplifier). Consequently, a GPS RF signal splitter must have provisions for managing the DC voltage to the active GPS antenna. The S14GT and S18GT 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.

    “Distributed antenna systems allow for easy system growth in size and scope of application, whether the system needs to scale to reach new service areas or add bandwidth and capacity,” said Robert Horton of GPS Source. ” This growth has led to a strong demand for cost effective solutions that support GPS synchronization, an area where we are specialists. GPS Source brings leading-edge technologies and addresses major GPS/GNSS challenges faced by carriers and system integrators.”

    The S14GT and S18GT are in production and will be available January 2016. A CE Mark approval from the European Notified Body for these two devices will be available afterward.

    The new PXC021-V2 by Filtronic is a wideband cellular + GPS low-loss splitter/combiner.

    Designed for repeater/DAS applications, the PXC021-V2 provides GPS L1 and L2 frequency coverage and wideband cellular frequency coverage (618-960 MHz and 1695-2690 MHz). It has low loss (≤ 0.30 dB Cellular and ≤ 0.70 dB GPS) and excellent cellular to GPS isolation (≥ 55 dB).

    The L1/L2 Channel Absolute Group Delay is 20 nS maximum (17 nS typical), and the variation is 4 nS p-p maximum over the L1/L2 bandwidth. The

    The PXC021-V2 is IP67-rated for outdoor use.

    GPS Source Adds to GPS Rackmount Splitter Line

    GPS Source has released a GPS/GNSS rackmount splitter with dual antenna inputs and antenna health monitoring. Developed for the wireless industry, the dual-input splitter provides a GPS timing signal to up to 32 GPS/GNSS synchronization modules and receivers. Its design ensures the GPS timing signal is always available, even in the event of an antenna or cable failure, the company said.

However, the new splitter also includes dual GPS antenna input ports, a health monitor and sensor switch. Up to 32 GPS/GNSS receivers or timing synchronization modules can access the signal at one time. Antenna redundancy is acquired through the use of primary and backup antennas. The sensor monitors the health of the primary antenna connected to the splitter. Based on the information provided by the sensor, the splitter will automatically switch antennas. The ability of the splitter to switch antennas allows all connected GPS devices to remain fully functional in the event of an antenna failure, which is important in today’s wireless environment.

    “The demand for high-speed wireless internet and data network access over a wide area has grown at a record pace,” said Robert Horton, CEO of GPS Source. “This growth has led to a strong demand for solutions that support more than one function because of limited space and increased usage. The new rackmount splitters, RMS216 and RMS232, will keep multiple timing synchronization modules operating for an extended period when a GPS antenna or cable fails. This extended period gives a solution provider supporting a cell site, base station, or DAS network, the ability to identify and fix any GPS/GNSS antenna or cable problem before other challenges arise.”

  • Optical Zonu Fiber Optic GPS Signal Distribution System

    The GPS Fiber Optic Distribution system from Optical Zonu connects up to 32 remote locations, transporting GPS signals from a single antenna to as many as 32 GPS receivers (or multiple antennas to multiple receivers). A common example of this application is a campus scenario where installing multiple GPS antennas is impractical. This particular system consists of the OZC J‐Series 5‐Slot modular 1U chassis. The Master Unit is located within close proximity of the GPS antenna and it contains modular and hot‐swappable fiber optic transmitter, AC power supply and J Optical Splitter cards. The remote unit is a stand‐alone (wall mountable) unit. It comes in a low profile semirugged package. A single 1U chassis at the master site is capable of supporting up to 32 remote locations.

    The optical transmitter module has built‐in LNA for high sensitivity detection of low level GPS signals. The Master Unit also has a Bias‐T to provide DC power to the GPS Antenna. Local monitoring is also integrated into the Master Unit, which is accessible via a single computer interface terminal. The maximum RF input signal into the transmitter is ‐25 dBm and the RF interface is via a 50 Ohms SMA connector. The standard optical connector is SC/APC (FC/APC is also available upon request) for low back reflection applications. The system is designed to operate on single mode fiber but may be custom configured to work on multimode fiber. The system is configured for complete dual redundancy, including additional fiber optic Tx module for a second GPS antenna.
