Feedforward Amplifiers for Wideband Communication Systems

Feedforward Amplifiers for Wideband Communication Systems has been possible thanks to the research carried out throughout several years in the field of the linearization techniques applied to digital communication systems, particularly to those with high spectral efficient modulation techniques. The wireless telecommunications are more and more demanded for the Information Society. Such requirements are reflected as a great many of communication standards with specific coverage applications and, above all, with higher and higher data transmission rates.

The electromagnetic spectrum, nevertheless, is a scarce asset that can not be spread and despite the increasingly tendency to transmit in higher frequencies, the bandwidths assigned to each application are always exploited to the limit.
