Dynamic load modulation and digital predistortion techniques are employed for improving the characteristics of classical I/Q transmitters under wideband communication formats, while envelope tracking implementation details are considered for further improving average efficiency in those architectures according to current available technology. Finally, advances in the RF path design of the emerging polar transmitter topology are also presented.}, publisher = {URSI 2010, XXV Simposium Nacional de la Unión Científica Internacional de Radio, Bilbao}, title = {Arquitecturas de transmisión inalámbrica de alta eficiencia}, author = {García García, José Ángel and Mingo Sanz, Jesús de and Montoro López, Gabriel and Cabria de Juan, Lorena and Marante Torres, Reinel and García Ducar, María Paloma and Sánchez Pérez, César and Bertran Albertí, Eduard and Gilabert Pinal, Pere Lluís}, }
