900 MHz DDS/PLL在矿井无线通信系统中的应用
Application of 900 MHz DDS/PLL to mine wireless communication system
【摘要】 矿井无线通信的一个发展方向是以甚高频为主的矿井无线通信。在甚高频系统中 ,射频的的频率合成器部分采用DDS/PLL技术。DDS/PLL可实现频率范围宽、频率转换速度快、频率分辨力高、相位噪声低和杂散小
【Abstract】 A development tendency of the mine wireless communication is a mine wireless communication mainly based on ultra high frequency. In the ultra high frequency system, the frequency compounder section of the transmitting frequency is operated with DDS/PLL technology. DDS/PLL can have a wide frequency scale, a fast frequency transmitting speed, a high frequency resolution, a low phase noise and a low phase stray.
