| description |
In the future communication systems, it is of key importance that the transceivers are capable of operating in multiple frequency bands and with complex signals. In this context, the power amplifier is a critical component of the transceiver, since it is responsible for most of the total power consumption in base stations and portable devices. Apart from the power consumption, the design of power amplifier systems must account for multi-band/broadband capabilities, high peak-toaverage power ratio signals and the mismatch effect caused by the various operating conditions. Hence, the design of power amplifier topologies that enhance the total system efficiency and reliability is a challenging task. This PhD dissertation introduces novel power amplifier architectures and solutions for modern communication systems. The contributions of this thesis can be divided in two parts. The first part deals with the study and design of power amplifier systems. It is of major importance that these designs provide linear amplification and operation at multiple frequency bands, which will permit the reduction of the cost and size of the devices. Additionally, we investigate the possibility to harvest the dissipated power from the power amplification process. For the development of the prototypes, lumped-element topologies, transmission line implementation and Substrate Integrated Waveguide (SIW) technology are adopted. In the second part of the thesis, novel matching networks are introduced and their properties are studied. In particular, resistance compression topologies are proposed to overcome the performance degradation associated with the sensitivity of nonlinear devices to environmental changes. These networks can be adopted in modern power amplifier architectures, such as envelope tracking and outphasing energy recovery power amplifier topologies, in order to provide improved performance over a wide range of operating conditions. |

En este contexto, el amplificador de potencia es un componente crítico del transceptor dado que su consumo energético supone la mayor parte del consumo tanto de las estaciones base como de los dispositivos móviles. Aparte del consumo energético, los nuevos diseños de sistemas de amplificación de potencia deben considerar aspectos como la capacidad de operar en múltiples bandas o en banda ancha, el uso de señales con alta relación de potencia pico a potencia media (PAPR) y el efecto de desadaptación que aparece bajo las diferentes condiciones de funcionamiento. Por lo tanto, el diseño de nuevas topologías para amplificadores de potencia que mejoren la eficiencia total del sistema y la fiabilidad es una tarea compleja. Esta tesis doctoral presenta nuevas arquitecturas de amplificadores de potencia y soluciones para los sistemas de comunicación modernos. Las contribuciones de esta tesis se pueden dividir en dos partes. La primera parte se centra en el estudio y diseño de sistemas de amplificación de potencia con el fin de proporcionar amplificación lineal y funcionamiento en múltiples bandas de frecuencia, lo que permitirá reducir el coste y tamaño de los dispositivos. Además, se investiga la posibilidad de reutilizar la energía disipada en el proceso de amplificación de potencia. Para el desarrollo de los prototipos, se utilizan topologías hibridas, implementaciones con líneas de transmisión y tecnología de guía de onda integrada en sustrato (SIW). En la segunda parte de la tesis, se proponen redes de adaptación y se estudian sus propiedades. En particular, se proponen topologías de compresión de resistencia para minimizar el efecto que producen en el rendimiento la sensibilidad de los dispositivos no lineales a los cambios ambientales. Estas redes pueden ser utilizadas en arquitecturas modernas de amplificadores de potencia como pueden ser las topologías envelope tracking y outphasing energy recovery con el fin de proporcionar un rendimiento mejorado bajo múltiples condiciones de funcionamiento.Universitat Politècnica de CatalunyaVerikouskis, ChristosGeorgiadis, Apostolos20142014-12-1520152015-01-13doctoral thesishttp://purl.org/coar/resource_type/c_db06VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/doctoralThesisapplication/pdfhttps://hdl.handle.net/2117/95569https://dx.doi.org/10.5821/dissertation-2117-95569reponame:UPCommons.
