ELECTRICAL CONNECTIONS
Warning – Operating without antenna or dummy load (50ohm) can permanently damage to the RF power transistor.
Warning – Check the output connection before applying DC voltage to the module.
HEATSINK MOUNTING/HARDWARE
Warning – This module must be place on a heat sink that is at least 160X80X30 mm
If the module will be over heated above 50°C – Air fan should be applied to the heat sink.
Warning – Overheating can cause permanently damage to the power transistor.
