The new communication standards like UMTS increase the spectral efficiency but a high linearity is required. RF power amplifiers are basic components of all wireless transceivers used in the communication systems, and their efficiency directly influences on the complete communication system efficiency. It is proposed the implementation of a linearization technique like feedforward to achieve lower cost and higher efficiency amplifiers with the same linearity. First, it is shown an adjusting… CONTINUE READING
