摘要
基于智能家居的应用场景,采用TI公司低功耗芯片CC2530作为核心器件,设计了一种Zig Bee无线通信系统射频模块。设计满足Zig Bee模块小型化结构的要求,给出了模块系统硬件框架,并根据该系统框架设计了外围电路、巴伦匹配电路以及Zig Bee印制倒F天线。采用分离电抗元件实现巴伦匹配网络以实现Zig Bee模块差分信号到单端信号的转换以及射频信号阻抗匹配。采用HFSS电磁仿真软件对Zig Bee天线进行建模和仿真。所设计的Zig Bee模块具有低功耗、结构小型化、低成本等特点。
A wireless communication system model for Zig Bee,based on the chip CC2530,using in the smart home circumstance,is designed in this paper.The block diagram of hardware circuit for Zig Bee wireless system which satisfies miniaturiazation of structure is proposed.The peripheral circuit,balun circuit and a miniaturized Inverted-F antenna are designed based on the proposed frame work.The balun circuit realized by separate components converts differential signals to single-ended signal.The printed Inverted-F antenna for Zig Bee is modeled by electromagnetic simulation software of HFSS.
