GPS Antenna Signal Splitter, 2 Way, SMA

GPS splitter used for powering active antenna and splitting GPS signal between two receivers

Overview

GPS212 is a two way, passive, GPS signal splitter ideal for splitting a GPS signal two ways from a separately powered signal source. Furnished with SMA female connectors all ports. A special feature of this unit is the 200 ohm internal load which provides a current drain for the GPS receivers. Some GPS receivers incorrectly sense an antenna fault when there is no current draw. The 200 ohm internal load provides a simulated antenna current drain which prevents receiver faulting. Max voltage rating at the DC blocked ports is 15 VDC; maximum current rating is 75 mA.

Electrical

The heart of the unit is a precision designed and etched Wilkinson type microstrip circuit on a low loss, high frequency, dielectric substrate. Electrical performance is highlighted by 0.4 dB max insertion loss (above the -3.01 dB power split), 22 dB min isolation, 1.25:1 max input VSWR and 1.15:1 max output port VSWR. Equal power split and symmetry is displayed by 0.2 dB amplitude balance and 3 degrees phase balance. Narrow band GPS performance in your band of interest may be even better. See 2 way GPS splitter test sweeps for details. DC block and 200 ohm internal load are specially designed to be RF transparent with negligable effect on performance.

Mechanical

Mechanical features include precision CNC, brass, 50 ohm SMA female coaxial connectors with tri alloy plating to insure tarnish resistance and low PIM operation. Connector pins are gold plated phosphor bronze for reliability and low contact resistance. Virgin electrical grade PTFE support insulators captivate the contact pins enabling trouble free coaxial connector mating. Long term operation and superior shielding is assured by the rugged CNC machined aluminum housing with clear chemical film finish. Secure mounting is provided by two 0.125" dia (3.18 mm) through holes. RoHS compliant construction includes no-lead solder and a finish free of hexavalent chromium.

Physical

Housing dimensions are 1.98" wide by 1.98" deep by 0.88" high (50.3 x 50.3 x 22.2 mm). The SMA female (jack) connectors extend 0.44" (11.1 mm) from the housing. Operating temperature range is from -65°C to +85°C. Weight is 133 grams. See 2 way GPS signal splitter outline drawing for more information.

Applications

Model GPS212 is a 2-way, passive, SMA, GNSS splitter covering all frequencies from 1000 to 2000 MHz with best-in-class performance for GPS L1, L2, L3, L4, L5, GLONASS and Galileo global navigation satellite positioning system applications, and is deployed worldwide.

Options / Additional Models

DC Blocking: Two DC blocking versions of this 2 way GPS splitter combiner available without the 200 ohm internal load:

PD5120: DC pass 1 port, DC block other port. Typically used for powering an active antenna through the DC pass port of the RF power divider splitter.

PD5122: DC block 2 ports. Typically used in combining applications to prevent passing DC to sum port or adjacent port.

Standard RoHS Model: A standard RoHS compliant version of this two way power combiner divider is available passing DC current through all ports. PD2120
