GPS Splitter

GPS antenna splitters eradicates the requirement to run a number of antenna cables coming from quite a few antennas by running a single cable and splitting it with the aid of antenna splitters, making the site installation convenient and affordable.

Certain GPS splitters have amplifying properties which allows them to run long cables preceding the splitter. The splitter amplification, the cable type as well as the antenna specifications, determines the maximum cable length that should be used.

The LDCBS 1X2 GPS antenna-splitter is built with a power splitter of 1 input – 2 outputs. This feature is specifically designed for certain GPS frequencies such as GLONASS, L1 and L2 carrier frequencies. In order to avoid causing damage to the antenna, the J2 output leg happens to be DC-blocked. It consists of a grounded DC load, rated 200 ohm, as well, in order to mimic the pre-amp current draw of a GPS antenna. The J1 output leg serves as a DC supply in order to provide power to the antenna.

Features of the GPS Antenna Splitters include:

  • Produces high quality Gain flatness
  • Phase matched outputs, phase (J1-J2) < 1.0o
  • The Group Delay is extremely Flat which is less than 1ns variation

The ALDCBS1X4 GPS Amplified Splitter is a device designed with 1 input, projecting to 4 outputs along with a “gain block” supporting a minimum of 17dB. It is designed to respond to the L1 and L2 GPS frequency bands with outstanding gain flatness. To power the antenna and the splitter amplifier, the splitter Radio Frequency (RF) output (J1) passes Direct Current (DC) from the GPS receiver, which is connected to it within a normal configuration. To simulate the antenna current draw, the J2, J3 and J4 RF outputs consist of a DC load with a resistor rated 200 Ohm.

Features are as follows:

  • Group Delay is extremely Flat, less than 1ns variation
  • Outputs are phase Matched, Phase (J1-J2) < 1.0o
  • Amplifier Gain of 17Db, Gain = 17dB

The ALDCBS1X8 GPS antenna splitter consists of an amplified power distributor of 1 input to 8 outputs. It is specifically designed to respond to the GLONASS, L1 and L2 carrier frequencies where the J2 to J8 (seven output legs) are DC-blocked in order to avoid damage to the antenna. It consists of a grounded 200 ohm DC load, in order to mimic the pre-amplifier current draw. The output leg (J1) is a DC-short in order to provide power to the antenna.

Features are as follows:

  • A 13dB Amplifier Gain, Gain = 13 dB
  • Outputs are Phase Matched, Phase (J1-J2) < 1.0o
  • Extremely Flat Group Delay, Less that 1ns variation

GPS Active Splitters
These splitters provide reliable signals. A number of GPS receivers are allowed by the Symmetricom’s Active Splitters in order to share a single antenna. They are designed for production and position/timing verbosity applications enabling the provision of reliable signals for two, four or eight GPS receivers.

The Symmetricon Active Splitters are capable of providing the required amount of GPS-L1 signals to large companies. The built-in amplification property helps to overcome the splitter losses and the Active Splitters are able to conveniently descend without the addition of separate amplifiers as well as the bias-tees between splitters.

The GPS receiver(s), which are connected to the amplifier, obtains power conveniently, as a result, eliminating the requirement for a separate wiring and a dc power supply. An active antenna uses the DC power, which is applied to the splitter, as a result, simplifying the installation.

The GPS receiver supplies power to the 58536A (4 outputs), 090-58537-01 (4 outputs) and 58535A (2 outputs) when connected to any port. The GPS receiver connection in port 1 supplies power to the 58517 (8 outputs) also consists of an external DC supply (optional) when required.

The review above illustrates the functions of the GPS antenna splitter categorically.
