摘　　要：无线通信技术在卫星通信、军事雷达、移动终端等领域获得了广泛应用,在卫星导航系统中,天线接收到的多路信号需要进行处理后传输到基带处理器。接收组件对天线接收信号的处理质量直接影响导航定位精度,L波段的多通道接收组件采用通道隔离技术将天线接收的多路信号进行选频、放大、滤波、下变频处理,得到两种各四路具有高增益、高通道间隔离度、高相位一致性等特点的中频信号,最终传输到基带进行处理。本接收组件具备可靠性高、抗干扰能力强等特点。Wireless communication technology has been widely used in areas such as satellite communication,military radar and mobile terminals.In satellite navigation system,the signals received by the antenna need to be processed and then transmitted to the base-band processor.The navigation accuracy is directly affected by the signal received by receivers.The technology of channel isolation has been used in the L-band multi-channel receiver,to realize signal processing,such as frequency-selecting,amplify,filtering and down conversion processing,then get two kinds of signal with different frequency.Each frequency has four channels,and the finally IF signal which transmitted to the base-band processor has the characteristics of high gain,high channel isolation and high phase consistency.The receiver mentioned in this paper featuring high reliability and anti-interference ability.
