Intermodulation distortion in microwave and wireless circuits

Аннотация

This book deals with the nonlinear distortion phenomena seen in microwave and wireless systems. As its name indicates, nonlinear distortion is a form of signal perturbation originated in the system’s nonlinearities. To understand this concept, let’s suppose we want to send some amount of data from a transmitter to a receiver through a wireless medium, as shown in Figure 1.1. Under this scenery, we would naturally define signal perturbation as being any component, other than the sought data, the receiver detects, since it poses difficulties in the correct decoding of the information received. Signal perturbation can thus be either due to the addition of new components, or to the modification of the original signal characteristics.
