Figure C-4. GPS L1 1:4 Active Splitter
GPS/GLONASS/BeiDou Splitter
This L band frequency, RoHS compliant 4:1 active splitter makes it possible to use a
single GPS referencing antenna and cable arrangement for multiple
synchronization systems. The antenna DC bias select circuit allows for the active
antenna DC input to be applied to any or all RF outputs. One DC voltage will be
chosen to power the antenna while other inputs will be switched to DC loads. If the
selected DC bias input should fail, the DC bias will automatically switch to another
DC input to ensure an uninterrupted supply to the active antenna.
