Technical Trend of Multi-mode Multi-band RF Transceivers
Details
This paper describes resent technology trend of multi-mode multi-band RF transceivers. Thanks to advanced CMOS technology, not only single-mode transceivers, but multi-mode transceivers are now put to practical use. Furthermore, software defined radio transceivers which can be applied to many wireless systems are being realized. The evolution of RF transceiver technique is reviewed, and some multi-mode, multi-band transceivers are discussed including the technique to eliminate external components.
