Abstract： As military UAVs and other avionics systems continue to develop in the direction of miniaturization, intelligence, and integration, how to effectively meet the low SWaP (Size, Weight and Power) requirements of equipment has become a major problem. In this paper, the development of a certain type of broadband integrated digital preprocessing module is introduced, and the signal processing platform (DSP, FPGA, SerDes and DDR chip) is integrated by using the "bare chip + high-density substrate" system-in-package (SiP) method, which replaces the traditional method of "packaging chip + printed board + planar integration" commonly used in the industry, and realizes the high-density integration of broadband integrated digital signal processing module. Under the condition that the main performance indicators (programmable logic resources, fixed-point processing capabilities, floating point processing capabilities, and data transmission rates) remain unchanged, the area of the signal processing module is reduced to 45 mm×45 mm, and the weight is reduced to 103 g.

引言
隨著現(xiàn)代無線通信技術(shù)朝著數(shù)字化、寬帶化、綜合化和智能化方向的發(fā)展，軟件無線電處理平臺(tái)也變得更加復(fù)雜。某航空綜合射頻系統(tǒng)的數(shù)字預(yù)處理模塊是一個(gè)數(shù)字電路復(fù)雜系統(tǒng)，模塊采用的通用信號(hào)處理平臺(tái)也由原單通道增加為三通道結(jié)構(gòu)。而通道數(shù)的增加進(jìn)一步壓縮PCB布局空間，同時(shí)也對模塊功耗、可靠性和面積均產(chǎn)生嚴(yán)重影響。因此，如何最大限度的實(shí)現(xiàn)通用信號(hào)處理平臺(tái)的小型化、功能集成化以及輕量化，對降低系統(tǒng)功耗、提升可靠性、減少面積，滿足裝備的低SWaP（Size，Weight and Power）[1]等方面有十分重要的作用。
