Title: Feed forward amplifier
Inventor: SAKAI KAZUHIKO
IPC: H03F1/32
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To obtain a feed forward amplifier whereby the output signal of a level detecting circuit is made to be a min. value at high speed by executing adjustment so as to permit a signal which is injected by controlling a vector adjusting equipment to be the min. value. SOLUTION: The output signal of a main amplifier 4 is distributed to a signal route (c) and the signal route (d) by a distributor 21 and synthesized by a synthesizer 6. The distortion component of the main amplifier 4, which is taken-out by the synthesizer 9 is canceled by permitting amplitude and a phase to be the same amplitude and the opposite phase in the signal route (c) and the signal route (d) so that the output signal with no distortion from an output terminal is obtained. The vector adjusting equipment 10 is controlled by a control circuit 17 so as to permit a pilot signal injected by a pilot signal injector 3 to be the min. one in the distributor 19 in order to obtain the same amplitude and the opposite phase in the signal route (c) and the signal route (d). Thus, a distortion removing loop is controlled at high speed and distortion occurrence is restricted to the min.
