GPSL18 Features & Benefits
Overview
GPSL18 is a two way, passive, GPS signal splitter ideal for splitting a GPS antenna signal between two receivers while blocking the DC current path from both devices. Max voltage rating at the DC blocked ports is 10 VDC; maximum current rating is 50 mA. Furnished with SMA female connectors all ports. Being a "micro-sized" splitter, GPSL10 weighs only 21 grams and is suitable for applications requiring low-weight parts.
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 0.3 dB max insertion loss (above the 3.01 dB power split), 18 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 0.1 dB amplitude balance and 2 degrees phase balance. Narrow band RF performance over your frequency range may be even better. See 2 way micro GPS splitter test sweeps for details. DC block is specially designed to be RF transparent with negligible effect on performance.
Mechanical
Mechanical features include precision CNC, brass, 50 ohm SMA female coaxial connectors with tri alloy plating to ensure tarnish resistance and low PIM operation.Connector pins are gold plated beryllium copper for reliability and lowcontact 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 construction includes no-lead solder and a finish free of hexavalent chromium.
Physical
Housing dimensions are 0.98" wide by 0.98" deep by 0.44" high (24.9 x 24.9 x 11.2 mm). The SMA female (jack) connectors extend 0.38" (9.5 mm) from the housing. Operating temperature range is from -65°C to +85°C. Weight is 21 grams. See 2 way Micro GPS signal splitter outline drawing for more information.
Applications
Model GPSL18 is a 2-way, passive, SMA, GNSS splitter covering all frequencies from 1164 to 1602 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.
