摘要：A linearization technique for reducing third-order intermodulation distortion that uses the injection of the fundamental signal second harmonics together with the fundamental signals at the amplifier input has been improved in this paper. The procedure proposed introduces phase correction of the fundamental signals according to the differences in phase of the second harmonics. Linearization technique has been applied on an muliichannel amplifier with four analog signals at input. As the result, the improvement in third-order intermodulation power level is 40 dB
