Improved Second Harmonic Linearization Technique for Multichannel Amplifiers with Enhancement Reducing in Intermodulation Distortion

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 tec...

Digital Predistortion for the Linearization of Power Amplifiers

High efficiency and linearity are indispensable requirements of power amplifiers. Unfortunately they are difficult to obtain simultaneously, since high efficiency PAs are nonlinear and linear PAs may have low efficiency. In order to satisfy the efficiency and linearity requirements, designers preferred to prioritize the efficiency of PAs in the design process and to later recover the linearity ...
