摘要： PROBLEM TO BE SOLVED: To provide a feed forward type distortion compensation amplification device capable of removing distortion components regardless of width of the frequency band of input signals.
SOLUTION: The input signal delayed by a relay circuit (DL) 5 and the input signal amplified by a main amplifier 2 are synthesized by a CDC7. Then the synthesized signal is taken out by a CDC8, which is separated into the signals of prescribed frequencies by band pass filters 20 and 22. The separated two signals are synchronous-detected with the input signal or its orthogonal signal at synchronous detection circuits 21 and 23, which are converted to control signals at a signal processing circuit 24, and fed back to the main amplifier 2. Thus, by adjusting gain or phase, or both, of the main amplifier 2, a distortion component is accurately extracted.

摘要： PROBLEM TO BE SOLVED: To provide a forward type distortion compensation amplifier which performs control in a correct direction even when phases of two received signals are deviated.
SOLUTION: The forward type distortion compensation amplifier directly utilizes an input signal to apply synchronization detection to the signal. That is, the amplifier uses the input signal or a prescribed band signal within a band of the input signal for a synchronizing signal to apply synchronization detection to a signal branched from a signal of a CDC 7 receiving an output signal of a CDC 6. Further, the amplifier converts both the input signal and the output signal of the CDC 6 into an intermediate frequency by using a signal from a local oscillator to apply synchronization detection to an intermediate frequency signal of the output signal of the CDC 6 by an intermediate frequency signal of the input signal.
