GPS161 is a sixteen way, passive, GPS signal splitter ideal for splitting a GPS antenna signal between twelve 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 others. Furnished with SMA type 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 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 10 VDC; maximum current rating is 50 mA. Maximum voltage rating at the DC pass port is 50 VDC; maximum 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 1.4 dB max insertion loss (above the 12.04 dB power split), 22 dB min isolation, 1.50:1 max input VSWR and 1.20:1 max output port VSWR. Equal power split and symmetry is displayed by 0.6 dB amplitude balance and 8 degrees phase balance. Narrow band GPS performance in your band of interest may be even better. See 16 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.
Housing dimensions are 15.98" wide by 3.48" deep by 0.88" high (405.9 x 88.4 x 22.2 mm). The SMA female (jack) connectors extend 0.65" (16.5 mm) from the housing. Operating temperature range is from -65°C to +85°C. Weight is 1690 grams. See 16 way GPS splitter outline drawing for more information.
