Amplificadores clase CE de doble banda con estructuras basadas en líneas CRLH y ECRLH.

摘要

In this paper the use of Composite Right/Left Hand (CRLH) and Extended Composite Right/Left Hand (ECRLH) transmission lines in dual band power amplifiers is proposed. The CE class power amplifier presents advantages over conventional amplifier such as larger efficiency and low bias supply and what it is more, the fact that it is the fundamental class in bipolar transistor. The design procedure and the design equations are presented. The non-linear phase response of a CRLH and ECRLH transmission line has been utilized to design arbitrary dual-band amplifiers. A design in dual-band CE class power amplifier illustrates the synthesis procedure.
