Antenna power output
Applicable receivers: | BD1090 | BD1092 | BD1092i
Each antenna connector can supply DC power independently. Each output is supplied by a dedicated boost regulator. Each antenna regulator can switch voltage between 5.5 V to 7.4 V by using a GPIO to change the feedback and can source a maximum of 150 mAmps. Switching is done to select narrow versus wideband filtering for MSS jam-immunity in capable Trimble antennas, and is automatically set based on the antenna type configured in the configuration and global location.
The output is protected through a PTC against short circuits. The PTC will trip at 150mA at +85C and >200mA at anything <70C. During a short-circuit event, the module may reset; however, this reset is avoidable if the input 3.3V power source can provide at least 4A of surge current.
