Title:
AMPLIFIER
Document Type and Number:
Japanese Patent JPH0722856
Kind Code:
A
Abstract:
PURPOSE: To provide an amplifier capable of preventing distortion when a signal is amplified. CONSTITUTION: The constitution has a main amplifier 143 and a pair of correcting amplifiers 147, 1411, and in the case of amplifying a high frequency composite signal having a multiplex sinusoid component, the amplifiers 147, 1411 delete different distortion components led into an amplified signal by the main amplifier 143. The constitution of another embodiment has a main amplifier and three correcting amplifiers, and in the case of amplifying a high frequency composite signal having a multiplex sinusoid component, these correcting amplifiers delete different distortion components led into an amplified signal by the main amplifier. The constitution can execute the deletion of different distortion components at a low distortion state as compared with a conventional device without increasing cost and manufacturing limits.
