Abstract: To address the high integration, miniaturization, and lightweight requirements of phased array Transmit/Receive (T/R) subarrays in military equipment, this paper focuses on the research of Quad Flat No-lead (QFN) plastic-encapsulated T/R module technology. This approach aims to solve issues associated with traditional metal-packaged microwave modules, such as large form factors, numerous connectors, structural parts, printed circuit boards, assembly processes, and high costs. By conducting electromagnetic simulation design for key packaging parameters, the study addresses the poor high-frequency performance of existing plastic encapsulated products, achieving a chip-level integration of the Ku-band T/R module without connectors or enclosures. The overall dimensions of the 4-channel Ku-band T/R module are 12 mm × 6.6 mm × 0.75 mm, with a weight of 0.22 g. The measured electrical performance meets application requirements, providing a low-cost, high-performance, miniaturized, and thin technical solution for next-generation phased array radar systems.

引言
现代战场环境日趋复杂,武器装备在作战时的机动性、可靠性和隐蔽性要求随之增高,传统封装相控阵天线系统存在外形尺寸大、装配工序多、成本高等问题,而具备低成本、小型化潜力的塑封系统级封装(System in Package, SiP)产品[1-5]在微波毫米波领域的研究也越来越多,目前国内研究中受限于高频性能差等行业技术瓶颈,相关成果较少,难以满足未来武器系统作战需求[6-8]。本文将塑封四边无引脚扁平封装(Quad Flat No-lead, QFN)工艺结合SiP多芯片集成技术,利用塑封产品优势有效解决传统收发(Transmit/Receive, T/R)组件在加工成本、共形集成等方面的问题,实现Ku波段T/R组件的高密度片式集成,形成通用标准化、轻量化、低成本、快速共形组阵能力,以支持下一代综合相控阵的大规模、多任务应用。
