Abstract :
This paper describes a radio transmitter architecture based on the LINC concept. It associates a digital RF modulator with highly selective compact filters and saturated power amplifiers. Despite its apparent complexity, this mixed digital/analogue system guarantees both linearity and high power efficiency while offering increased flexibility, reconfigurability and compactness. As a result, this architecture appears as a relevant choice for future opportunistic radio developments.
