本文介绍了 GS—110散射通信微波接收机的研制情况。该机用于西南电业管理局成渝线与成达线对流层散射通信设备中,以2048kbit/s 和1024Kbit/s 两种传输速率,传送64路和32路数字话。整机噪声系数<4dB(含天线预选泸波器),增益50dB,16部接收机各支路增益不一致性小于±1.5dB,带宽大于8MHz,经室内系统联试和实际开通使用证明,微波接收机性能良好,工作稳定可靠,使用维护方便。
This article describes the GS-110 development of the scattering communication microwave receiver. This machine is used in the troposcatter communication equipment of Chengdu-Chongqing Line and Chengda Line of Southwest Electric Power Administration to transmit 64-channel and 32-channel digital data at 2048kbit / s and 1024Kbit / s two transmission rates. The noise figure of the whole machine is less than 4dB (including the antenna preselected wave filter), the gain is 50dB, the gain inconsistency of each branch of 16 receivers is less than ± 1.5dB and the bandwidth is greater than 8MHz. After indoor system connection test and actual application, microwave reception Machine performance is good, stable and reliable, easy to use and maintain.
