With the evolution of wireless systems and services, the on-air signals themselves are also undergoing very significant transformations. This paper by Besser Associates instructor Earl McCune provides a survey of the active and coming-soon signal types adopted for wireless systems around the world. Focus is on modulation schemes, along with various measures used to characterize the signals before and after power amplification.

This book is based on the first three days of the Applied RF Techniques I course from Besser Associates. Basic analytical tools such as S-parameters and the Smith Chart as well as passive components are covered. Active components are covered in Volume II.
