What should the voltage be on the module's RF connector?
Hi, thank you for your question!😊
Actually, there's no standard voltage for the RF connector—it depends on the board design. For the K827, the antenna RF port voltage is between 3.0 V and 5.0 V. This voltage must match your active antenna's requirement. Too low, the antenna won't power on; too high, you might burn the LNA inside. To measure it, set your multimeter to DC voltage, touch the red probe to the center pin of the RF connector, and the black probe to the outer metal shell (ground).
