Title: High frequency power amplifier and amplification method, and semiconductor device
Inventor: SUZAKI HIDESHI
IPC: H03F1/52
Filed: 2008-03-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide a high frequency power amplifier which accurately detects a change in a gain, is immune to load variation and reduces nonlinear distortion in a mobile unit adopting a digital modulation scheme with amplitude variation.  <P>SOLUTION: A first detection circuit and a second detection circuit are connected to an input node and an output node of a final stage. Detection signals detected in the respective detection circuits are input to a differential amplifier circuit. The signal level difference output from the differential amplifier circuit does not change even if the input power varies. Because a change in the power gain at the output node does not travel back to the input node when the load impedance of a high frequency power amplifier varies, it is possible to detect only the change in the load impedance. Damage to the final stage can be prevented by controlling the operating current of the final stage and the gain of the drive stage according to the detected load variation. Furthermore, nonlinear distortion in the high frequency power amplifier can also be reduced by detecting the change in the gain of the drive stage and canceling the change in the gain of the adjustment stage.  <P>COPYRIGHT: (C)2009,JPO&INPIT

The portion to be bent is previously subjected to thickness deviation working in such a manner that the ratio of the wall thickness of the portion to be the back side of the curved pipe/the wall thickness of the curved pipe to be the ventral side of the curved pipe is ≥1.2. The working method performs high frequency bending by using the steel pipe and regulating the bending radius to (1.5 to 2.0) x (the external diameter of the pipe). The occurrence of the microcracks during working can be prevented.  <P>COPYRIGHT: (C)2010,JPO&INPIT
