<p>Disclosed is a noise removing apparatus for a wireless transceiver, the apparatus including a transmission-frequency control voltage generation unit for generating a transmission frequency control voltage to control a transmission frequency, which is used to convert a baseband signal to be transmitted into a signal having a transmission frequency band; and a band stop filter for preventing a transmission frequency band signal included in a received signal from passing therethrough, by controlling an attenuation pole to accord with the transmission frequency band, based on the transmission frequency control voltage. The noise removing apparatus can precisely and sufficiently remove a transmission signal included in a received signal by using the band stop filter. In addition, the wireless transceiver having the noise removing apparatus can prevent the occurrence of CM noise resulting from a transmission signal included in a received signal, by sufficiently removing the transmission signal included in the received signal.</p> |
