Future needs in RF reconfiguration from a system point of view (invited paper)

Development of reconfigurable RF resembles the Quest for the Holy Grail. It was started a long time ago; interesting developments have been achieved but it looks like it will never finish. However, as more and more microelectronic markets are under intense pressure, the need for reconfigurable RF systems is constantly growing. This paper aims at describing all current evolutions which push towards increasing reconfiguration capability of RF systems and will explain how this reconfigurability should be stated.
