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.
