ZigBee是一种低速无线个域网技术,适用于通信数据量小,速度相对较低,并且功耗低的场合。组网灵活是其一大特点,但是由于传输距离比较短,从而限制了其发展。基于ZigBee无线通信网络技术,提出了一种通过增大发射信号功率、提高接收信号灵敏度来增加系统传输距离的方法。使用ADS软件主要对功率放大电路和低噪声放大电路进行仿真与性能优化,从而得出最佳设计方案。仿真结果基本满足了系统功率和增益的要求。
ZigBee is a low-speed wireless personal area network technology, suitable for small amount of communication data, the speed is relatively low, and low power consumption. Flexible networking is one of its major features, but its limited development due to its short transmission range. Based on the ZigBee wireless communication network technology, a method is proposed to increase the transmission distance of the system by increasing the power of the transmitted signal and increasing the sensitivity of the received signal. Using ADS software mainly for power amplifier and low noise amplifier circuit simulation and performance optimization, resulting in the best design. Simulation results basically meet the system power and gain requirements.
