Patent 7313368 was granted and assigned to Industrial Technology Research Institute on December, 2007 by the United States Patent and Trademark Office.
The present invention relates to a dual band transceiver architecture for wireless communication. A high frequency integrated circuit is used for converting down the received multi-mode frequency signal, and then a decoding circuit for base frequency will perform the processes of up-sampling and emitting a signal so as to transmit/receive the dual band signal by using a single frequency synthesizer.
