[0035] For a transceiver device of the present invention, first, the transceiver is modularly divided according to the implementation process. On the basis of ensuring miniaturization and index performance of the transceiver, the same process is adopted for each module to ensure module reliability. Although modular division is carried out, the integration degree is reduced, but the size of each module is still much smaller than before and is still acceptable for most communication systems. Second, the transceiver is modularly divided according to functions, into task modules and general modules. The task modules are designed differently according to different requirements of the communication system, and the structures and interfaces adopt standardized designs; the general modules are designed for the general functions of the communication system and are adapted to different task modules in terms of structure and function.
