TP、XF系列户外型放大器是广东潮州市广播电视器材厂生产。采用进口飞利浦CATV专用IC组件,具有多频道邻频传输、输出电平高、频率范围宽、性能稳定、防雨防雷措施好、调试方便、价格低等特点,在我国城乡有线电视网络中应用很广。但出现故障后,维护人员不了解其工作原理,出厂时不带图纸,难以就地修复。聚积一起到外地维修,即耽误时间,又浪费人力和财力。笔者根据一些放大器的实物绘制出TP632—550A
TP, XF series outdoor amplifier is Chaozhou City, Guangdong Radio and Television Equipment Factory production. Imported Philips CATV IC components, with multi-channel adjacent-frequency transmission, the output level is high, the frequency range is wide, stable performance, rain and lightning protection measures are good, easy debugging, low prices, etc., in China’s urban and rural cable television network applications Very wide. However, after the failure, maintenance personnel do not understand its working principle, leaving the factory without drawings, it is difficult to repair on the spot. Accumulation together to the field maintenance, that is, the delay of time, but also a waste of human and financial resources. The author draws a TP632-550A based on some of the physical amplifier
