There is a gradual evolution toward integration of multifunction, multistandards in radio transceivers for wireless communications. Minimizing part count and cost is paramount. There are planned future services and evolved products, which contain both Cellular Communication and Wireless Connectivity features with Global and Nomadic roaming for voice and data. This workshop will first address the key requirements for each system. The suitability of the different transmitter and receiver types will be considered for the various systems highlighting their strong and weak points. Techniques to generate an all-digital transmitter frequency synthesizer, as well digital receiver reception will be reported. The goal is to find common transceiver architectures that are flexible whilst meeting the requirements of such systems. Recent advances in semiconductors, transceiver architecture, and state-of-the-art designs will be presented. Performance of each design will be highlighted with techniques to overcome their possible weak points.
