Abstract
Described are concepts, systems and techniques for detecting whether an impedance mismatch exists at an output port of a remote radio head (RRH) or at an output port of a radio frequency (RF) amplifier in an RRH such as may be caused by a faulty connection between an antenna and a transmit signal path of the RRH. Also described are means for protecting an RF amplifier or other active RF device in the transmit signal path from damage due to such a faulty connection.
