Abstract: An antenna front-end module, method, and information handling system are adapted to the application of a direct-current (DC) bias voltage in relation to an antenna and detect a connection status of the antenna based on a sensed DC voltage. When the connection status corresponds to the antenna being connected, a first transmit power level is configured. When the connection status corresponds to the antenna being disconnected, a second transmit power level is configured. A transmit power boost can be provided such that the first transmit power level is greater than the second transmit power level. The first transmit power level can correspond to a radiative transmission mode, and the second transmit power level can correspond to a conductive transmission mode.
