The invention discloses a universal interface 
system for a multifunctional radio-frequency module, and belongs to the technical field of communication. The universal interface 
system comprises a 
system control management module, a universal 
bus interface module and a universal radio-frequency module, wherein the system control management module communicates with the universal 
bus interface module through a synchronous 
bus, and is used for issuing a system message, a control command and data, and receiving and 
processing self-check and state information reported by the universal radio-frequency module through the universal 
bus interface module at the same time; the universal 
bus interface module is a bridge between the system control management module and the universal radio-frequency module, and is used for finishing forwarding and 
processing of a system control command and data forwarding; and the universal radio-frequency module is applied to receiving-transmitting and up / 
down conversion of radio-frequency signals and modulation and 
demodulation of 
baseband signals, and executing the control command issued by the system control management module. The universal interface system is applied to radio communication, navigation and monitoring systems. Through adoption of the universal interface system, the 
system integration testing amount can be reduced effectively, and the 
system stability is improved.
