DUAL BAND HIGH EFFICIENCY CLASS CE POWER AMPLIFIER BASED ON CRLH DIPLEXER

Abstract

In this paper, the most adequate architecture to implement dual frequency ampliflers is shown. Composite Right/Left Hand (CRLH) and Extended Composite Right/Left Hand (ECRLH) transmission lines are studied and evaluated to flnd the most suitable structure for dual band power ampliflers. As an example, the performance of a class CE amplifler, working in TETRA and GSM frequency bands, is compared with simulations and measurement, showing good agreement.
