Abstract: A linearizer has a dividing system for dividing a radio frequency signal into a first, second and third part. First and second transfer devices, each driven by the dividing system, can separately amplify the first and the second part of the signal. The first transfer device produces a higher distortion than the second with a distortion-producing, conditioning device. The second transfer device has, with respect to undistorted output components, a transfer characteristic whose output phase and amplitude substantially tracks that of the conditioning device during variations in amplitude. The first transfer device also has a retarding device serially coupled with the conditioning device for retarding signals handled at the conditioning device to produce approximately a 180 degree phase shift between the outputs of the first and the second transfer devices. A third transfer device is driven by the third part of the radio frequency signal from the dividing system.
