Description
Designed to eliminate the cost of multiple antennas and long cable runs in wireless base
stations applications, the S14WI can satisfy the demanding, high reliability requirements of the
wireless infrastructure market. The GPS Source S14WI is a high performance GPS signal
splitter that can be configured to monitor the GPS antenna current and provide an alarm
indication if the antenna is not operating according to spec. The S14WI also features an
optional antenna DC bias “Pick-&-Choose” circuit which allows for the active antenna DC input
to be applied to any or all of the RF outputs. With this option, one DC voltage will be chosen to
power the antenna while the other inputs will be switched to DC loads. If the selected DC bias
input should fail, the DC bias will be automatically switched to another DC input so as to ensure
an uninterrupted supply to the active antenna. The S14WI may be configured as a passive or
an active device, giving the network engineer the flexibility to specify the device gain and port-
to-port isolation. The S14WI may also be ordered with surge protection on all five ports and in a
sealed housing sufficient for many years of operation in external environments.
