Wireless signal transceiving apparatus
First Claim
1. 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.

Abstract
A wireless signal transceiving apparatus is provided. The wireless signal transceiving apparatus includes a signal transceiving-end circuit, a transceiving amplify module, an output amplify module, a mixer, a frequency selecting filter, switch modules a first base-band signal transceiver and a second base-band signal transceiver. The transceiving amplify module receives and amplifies a signal from an antenna or the mixer. The output amplify module amplifies the signal from the mixer. The frequency selecting filter filters the signal from the mixer, the first base-band signal transceiver or the second base-band signal transceiver according to the mode selecting signal. The first base-band signal transceiver and the second base-band signal transceiver receive the signal generated by the frequency selecting filter and/or respectively transmit the first and the second base-band output signal. The switch modules turn on or turn off transmission paths for the signal according to the mode selecting signal.
