Abstract
An apparatus for detecting output power from an amplifier (103) comprises a first controller (105) for controlling output power of a signal from the amplifier (103), a device (107) for measuring dc bias current/voltage at an output (115) of the amplifier (103), second controller (109) operative to set the first controller (105) to a setting corresponding to an output power at a finite level, and a detector (109) for determining whether or not there is output power from the amplifier based on the measured dc bias current/voltage at the setting of the first controller (105). In one embodiment, the first controller (105) is set at a setting corresponding to an output power level which is sufficient to at least partially saturate the amplifier (103).
