A wireless communication apparatus and the configuration method thereof are provided. The wireless communication apparatus includes: a baseband module for processing the baseband signal, which is located in a host device of the wireless communication apparatus; and a radio frequency (RF) module for receiving the RF signal according to the RF band and the spectrum mask and conducting signal transmission with the baseband module, which is replaceably connected to the host device. By detaching the RF module from the host device and providing the interface between the RF module and the baseband module of the host device, the wireless communication, apparatus can realize the wireless access by selecting the replaceable RF module according to the use requirement, and the application flexibility of the communication terminal is enhanced and the weight and bulk of the host device is reduced.
