Title: Distortion compensation amplifying device
Inventor: HORIKOSHI DAISUKE
IPC: H03F1/32
Filed: 2003-04-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide a distortion compensation amplifying device which does not reduce a gain in an input stage even if input power of a high frequency signal becomes small, and efficiency of a power source does not fall.  <P>SOLUTION: In the distortion compensation amplifying device, if the input power is large and the input signal exceeds a 1st threshold q1, the input signal is distributed into respective amplification elements AM1, AM2 arranged in parallel by a distributor, the distributed signals are amplified by the amplification elements, but if the input power is small and the input signal level does not exceed the 1st threshold value, switching elements SW1 to SW4 select one AM1 out of the amplification elements, and falling off of the gain in the input stage side of the selected amplification element can be removed because the input signal bypassing the distributor is given to the selected amplification element. A control part 44 stops power feed to not selected amplification elements, then power consumption can be reduced.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
