Abstract
The present invention relates to a non-linearity compensating circuit for high-frequency amplifiers comprising a branch coupler for dividing the input signal into two components, two high-frequency amplifiers, one operating in the non-linear region, the other operating in the linear region, and each receiving one of the two signal components from said branch coupler, and a signal synthesizing circuit for taking the vectorial sum of the two antiphase signals from the two amplifiers whereby the non-linearity compensating circuit provides an input/output characteristics which is just the opposite of the input/output characteristics of the high-frequency amplifier to be compensated. Basically, the non-linearity compensating circuit according to the present invention does not require long delay lines, variable attenuators or variable phase-shifters of a special design so that the whole circuit can be constructed in a microwave integrated circuit form which has a reduced power loss.
