摘要： An amplifier failure detection apparatus for a radio transmitter that has a function for compensating for amplifier distortion of the radio transmitter and a function for determining amplifier failure has occurred by detecting that the gain of an amplifier has dropped a set level or more, in which: a gain-detection unit detects the gain of the amplifier; an alarm-detection-level-generation unit, which has a table for storing alarm-detection levels that correspond to input-amplitude levels, generates an alarm-detection level that corresponds to an input-amplitude level; and a comparison unit compares the gain detected by the gain-detection unit with the alarm-detection level, and generates an alarm based on the comparison results.

摘要： Disclosed is a transmission amplifier having a distortion compensator for compensating for distortion of an amplifier; an amplifier for amplifying the transmit signal that has undergone distortion compensation; a feedback unit for feeding an output signal from the amplifier back to the distortion compensator; and a delay circuit for inputting the transmit signal to the distortion compensator upon delaying the transmit signal for a delay time equivalent to time required for the feedback signal to arrive at the distortion compensator. A delay time TDS of the feedback signal at the time of stand-alone operation of the transmission amplifier and a delay time difference &Dgr;T between delay times of the feedback signal at the time of stand-alone operation and at the time of parallel operation are stored in advance. The delay time TDS is set in the delay circuit at the time of stand-alone operation, and (TDS+&Dgr;T) is set in the delay circuit at the time of parallel operation.
