The invention belongs to the field of radiation source simulation, and relates to a wide instantaneous bandwidth simultaneous multifunctional radiation source system architecture, which comprises a dual-mode intermediate frequency signal generation subsystem and a multi-channel frequency conversion subsystem. The dual-mode intermediate frequency signal generation subsystem comprises a direct digital frequency synthesis module, a signal playing module and a broadband DA module. When multiple digital intermediate frequency signals need to be generated at the same time, the digital frequency synthesis module or the signal playing module is controlled to work at the same time or separately, and multiple different types of digital intermediate frequency signals are generated at the same time or separately and sent to the broadband DA module. And the wide-narrow band filter filters the analog intermediate frequency signal to ensure the signal quality. The design of the N up-conversion channels can realize simultane
