基于CC2530的ZigBee射频收发模块设计

Design of a RF Model Based on ZigBee Wireless Communication

采用TI公司CC2530芯片,设计了一种基于ZigBee无线通信系统射频模块.提出了ZigBee通信系统印制天线的小型化结构以及硬件系统框架,与传统ZigBee无线通信射频模块采用外接单极子天线相比具有低剖面、小型化等优势.射频收发模块原理图与PCB版图均采用Cadence软件进行设计.印制天线采用电磁仿真软件HFSS建模,仿真与实测结果均满足ZigBee通信要求.

A ZigBee wireless communication system based on CC2530 chip is designed in this paper. The frame work of a hardware circuit and a miniaturized antenna is presented. The printed antenna has the advantage of low profile and miniaturization if compared with the monopole antenna in the traditional ZigBee wireless communication system. Both the diagram and PCB layout are drawn by Cadence. The printed antenna is modeled by HFSS, the experimental results show that it can satisfy the design requirement of ZigBee wireless communication system.
