PURPOSE: An RF front end module for triple mode and band is provided to support not only a global positioning system (GPS) signal of 1.575 GHz, a Bluetooth signal of 2.4 GHz band and a WiFi signal but also a WiFi signal of 5 GHz band. CONSTITUTION: A Bluetooth-WiFi transceiving path (130) includes a Bluetooth receiving path, a WiFi receiving path of a second frequency band, and a WiFi transmitting path of a second frequency band. The WiFi receiving path of the second frequency band receives a WiFi signal of the second frequency band. The WiFi transmitting path of the second frequency band delivers the WiFi signal of the second frequency band to a triplexer. A WiFi transceiving path (140) includes a WiFi receiving path of a third frequency band and a WiFi transmitting path of the third frequency band. The WiFi transmitting path of the third frequency band delivers a WiFi signal of the third frequency band to the triplexer.
