Patent ID: 8582629

Claim:
A wireless signal transceiving apparatus, comprising: a signal transceiving-end circuit, coupled to an antenna; a transceiving amplify module, coupled to the signal transceiving-end circuit, receiving and amplifying a receiving signal transmitted from the antenna, or amplifying and transmitting an output signal to the signal transceiving-end circuit; an output amplify module, coupled to the transceiving amplify module and the signal transceiving-end circuit, amplifying and transmitting the output signal to the signal transceiving-end circuit; a mixer, coupled to the transceiving amplify module and the output amplify module, receiving the receiving signal which is amplified and mixing the receiving signal to generate a mixed receiving signal, or mixing a preamble output signal to generate the output signal; a frequency selecting filter, coupled to the mixer, filtering the mixed receiving signal or filtering one of a first and a second base-band output signal to generate the preamble output signal according to a mode selecting signal; a first switch module, coupled between the mixer and the frequency selecting filter, transmitting the mixed receiving signal to the frequency selecting filter or transmitting the preamble output signal to the mixer according to the mode selecting signal; a first and a second base-band signal transceivers, coupled to the frequency selecting filter, wherein the first base-band signal transceiver receives the mixed receiving signal which is filtered and/or transmits the first base-band output signal, the second base-band signal transceiver receives the mixed receiving signal which is filtered and/or transmits the second base-band output signal; and a second switch module, coupled among the first base-band signal transceiver, the second base-band signal transceiver and the frequency selecting filter, the second switch module turning on a transmitting path for the first base-band output signal, the second base-band output signal and the mixed receiving signal which is filtered according to the mode selecting signal.
