摘要

Due to the rapid increase of wireless services below 6GHz, multi-band multi-mode wireless terminals are becoming popular. In this paper, up/down-conversion schemes are reviewed, in addition the pros and cons are discussed. At the present, direct conversion scheme is the most appropriate for both transmitters and receivers of these terminals which are able to cover the 0.4-6GHz RF frequency range and various modulation schemes. An example of multi-band multimode direct conversion Si-RFIC transceiver is introduced which was developed for 0.4-6GHz cognitive radio terminals.
