A dual-mode WLAN module includes two dual-band antennas (43a, 43b), an RF front-end circuit (4), a dual-mode radio frequency integrated circuit (RFIC) chip (3), a dual-mode Base-Band integrated circuit chip (2), and an interface (mini-PCI, PCI, USB etc.) connecting to a computer (1). The RF front-end circuit for dual-mode WLAN module comprises two transmitting circuits, two receiving circuits, switch units, and logic control circuit (40) for controlling the operation of transmitting/receiving selection and antenna diversity selection.
