一种毫米波瓦式T/R组件专用芯片架构
|
摘要
毫米波有源相控阵瓦式T/R组件工作频率高、波长短、单通道布局空间小,对T/R组件芯片级和子阵级集成设计提出不小挑战。相比而言,芯片级一次集成在提高集成密度、降低组件成本方面具有明显优势。文中根据瓦式T/R组件的布局特点,在芯片级集成层面,提出一种可灵活扩展、兼顾不同半导体工艺优势、功能划分合理的专用芯片集成架构。该架构在满足链路指标的前提下,可实现单通道芯片数量占比3/4只、面积占用不到3.7mm~2,显著提高了芯片级集成密度和功能密度,降低了T/R组件单通道实现成本,适用于毫米波频段任意规模的相控阵天线的高效扩展集成。
The tile T/R module for millimeter wave active electronically scanned array(AESA) has the characteristics of higher frequency, shorter wave-length and narrower space between two adjacent channels, and is facing the challenges of chip-level and sub-array-level integrating designs. Chip-level integration has obvious advantages for enhancing integrated density and reducing cost. According to the tile module's characteristics, a special chip topology is proposed, which has notable values such as flexible extending ability, compatibility for different semiconductor technology, and reasonable configuration for T/R chain's functions. By using this topology, a single T/R channel can be realized only by 3/4 chip and area under 3.7 mm~2. This is very useful for reducing cost and assembling difficulty, and can be applied in extending integrations for millimeter wave AESA.
