Abstract: Aiming at the design requirements of miniaturization and modularization of X-band multi-wave phased array components, this paper designs a SiP receiving module combining multi-chip module technology and microwave millimeter wave high-density vertical interconnection technology. Using HFSS to optimize the design of the semi-open quasi-coaxial structure, and using the three-dimensional layout of the double sided multi-cavity, the ML-SL-SL-CPWG and ML-SL-CPWG were designed as the no-lead pins for the X-band receiving SiP module. Receiver component gain≥32.8 dB, noise figure≤3.0 dB. And the module volume is only 12.5 mm×15 mm×5.4 mm,which is 63% area smaller and 76% volume smaller than the original two-dimensional planar system. At the same time, modular design has great advantages in system application.

    組件作為相控陣系統(tǒng)核心關(guān)鍵部分,占據(jù)著整機(jī)尺寸的一大部分,其成本甚至可以高達(dá)整個(gè)相控陣系統(tǒng)的60%[1]。隨著射頻微波電路的快速發(fā)展,傳統(tǒng)的二維獨(dú)立封裝集成方式很難滿(mǎn)足現(xiàn)在系統(tǒng)需求,對(duì)組件模塊的小型化、多芯片模塊技術(shù)(Microwave Multi-chip Module,MMCM)、系統(tǒng)級(jí)封裝(System in Package,SiP)以及射頻鏈路三維集成提出了更高的要求[2]。針對(duì)當(dāng)前復(fù)雜的電磁環(huán)境以及全空域多波束的測(cè)控需求,研究和設(shè)計(jì)體積更小、成本更低、性能更優(yōu)、可靠性更高的組件具有重要意義。

    本文應(yīng)用SiP技術(shù)中多芯片封裝技術(shù)(Multi-Chip Package,MCP)將X頻段接收組件射頻鏈路進(jìn)行了如圖1所示的上下腔三維小型化高密度封裝,大大縮減了組件模塊體積,可實(shí)現(xiàn)對(duì)X頻段左、右旋來(lái)波信號(hào)的濾波、低噪聲放大、數(shù)控移相及衰減,最終形成四波束輸出,供后端進(jìn)行數(shù)據(jù)處理。
