Filed: 2002-07-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide a distortion compensated amplifier in which a stable distortion compensation control operation is performed while suppressing fluctuation of power consumption to a minimum although there is a problem that a conventional distortion compensated amplifier is not stably operated since the entire power consumption of the amplifier is instantaneously increased in comparison with power consumption during distortion control convergence when a power source is turned on while a high frequency signal is inputted.  <P>SOLUTION: In a preamplifier means 1, a signal level of an inputted high frequency signal is detected by a detector 5 and when the power source is turned on, a control circuit part 28 attenuates the high frequency signal by controlling an attenuation quantity of a variable attenuator 2 to be larger than a specific attenuation quantity based on the input signal level detected by the detector. When it is detected that optimization is performed by a distortion detection loop means and a distortion removal loop means, in the distortion compensated amplifier, the high frequency signal is attenuated by controlling the attenuation quantity of the variable attenuator 2 to be the specific attenuation quantity, then amplified and inputted to the distortion detection loop means.  <P>COPYRIGHT: (C)2004,JPO
