1. A dual band transceiver architecture for wireless communication comprising:
- a first transmitting/receiving antenna for receiving and emitting a band signal of 2.4 GHz, and connected to a first band-pass filter and a first switch, and connected to a first power amplifying device and a first balance/imbalance device by switching the switch;
a second transmitting/receiving antenna for receiving and emitting a band signal of 5 GHz, and connected to a second band-pass filter and a second switch, and connected to a second power amplifying device and a second balance/imbalance device by switching the switch;
a high frequency integrated circuit connected to the power amplifying device via the two balance/imbalance devices for receiving the signal transmitted from the first transmitting/receiving antenna and the second transmitting/receiving antenna;
wherein a single frequency synthesizer will accomplish the modulation and transmission for the signal by applying the mentioned units.

Abstract
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.
