GPSL12 Features & Benefits
Overview
GPSL12 is a two way, passive, GPS antenna signal combiner ideal for combining signals from two active GPS antennas for use with a single receiver or timing device. Maximum voltage rating is 50 VDC; max current rating is 1000 mA. Furnished with SMA female connectors all ports. Being a "micro-sized" combiner, GPSL12 measures only 25x25x11.4 cm & weighs only 21 grams and is perfect for applications requiring low mass.
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 antenna combiner test sweeps for details.
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 GPSL12 is a 2-way, passive, SMA, GNSS combiner 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.
