A communication device is disclosed, having a wireless LAN transceiver, a wireless LAN demodulation circuit, a Bluetooth transceiver, a Bluetooth demodulation circuit, an oscillator, and a mixer. The wireless LAN transceiver conducts communication in a first frequency band and the wireless LAN demodulation circuit demodulates the wireless LAN signals. The Bluetooth transceiver conducts communication in a second band and a third frequency band, which are higher and lower than the first frequency band, respectively. The oscillator generates oscillating signals. The mixer mixes the signals in the second frequency band with an oscillating signal, which is higher than the second frequency band, and mixes the signals in the third frequency band with another oscillating signal, which is lower than the third frequency band to generate mixed signals. The Bluetooth demodulation circuit demodulates the mixed signals of the mixer. |
