GPS421 - Features & Benefits
GPS421 is a four way, passive, GPS signal splitter ideal for splitting a GPS antenna signal between two receivers while providing a DC current path to power a remotely located active GPS antenna from one receiver while blocking the DC path from the other. Furnished with TNC female connectors all ports. A special feature of this unit is the 200 ohm internal load which provides a current drain for the GPS receiver not powering the active antenna. 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. Max voltage rating at the DC pass port is 50 VDC; max current rating is 2000 mA.
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 0.6 dB max insertion loss (above the 6.02 dB power split), 22 dB min isolation, 1.35:1 max input VSWR and 1.20:1 max output port VSWR. Equal power split and symmetry is displayed by 0.3 dB amplitude balance and 3 degrees phase balance. Narrow band RF performance over your frequency range may be even better. See 4 way power divider test sweeps for details.
Mechanical features include precision CNC, brass, 50 ohm TNC female coaxial connectors with tri alloy plating to insure tarnish resistance and low PIM operation. Connector pins are gold plated beryllium copper 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" diameter (3.18 mm) through holes. RoHS construction includes no-lead solder and a finish free of hexavalent chromium.
Housing dimensions are 4.48" wide by 3.28" deep by 0.88" high (113.8 x 83.3 x 22.2 mm). The TNC female (jack) connectors extend 0.61" (15.5 mm) from the housing. Operating temperature range is from -65°C to +85°C. Weight is 585 grams. See 4 way outdoor GPS splitter outline drawing for more information.
Model GPS421 is a 4-way, passive, TNC-jack, 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
Standard Version: A standard version of this three way GPS splitter is available passing DC all ports and spanning 698-2700 MHz for L-Band, Public Safety Band, and 3G/4G LTE applications. PD2940
DC Blocking: Two DC blocking versions of this 4 way GPS splitter combiner available without the 200 ohm internal load:
PD5940: DC pass 1 port, DC block other ports. Typically used for powering an active antenna through the DC pass port of the RF power divider splitter.
PD5942: DC block 4 ports. Typically used in combining applications to prevent passing DC to sum port or other input.
Indoor GPS Splitter: 1x3 GPS antenna signal splitter covering GPS / GNSS global navigation satellite system positioning frequency bands without silicon o-rings for indoor use. GPS420
