中国CATV470MHz全频道频率合成电子调谐器的设计

Design of China CATV 470MHz Frequency Synthesis Tuner

介绍了中国ＣＡＴＶ４７０ＭＨｚ全频道频率合成电子调谐器的设计方法．对ＵＨＦ频段的噪声系数和本振温度飘移问题进行了分析与讨论。

In this paper,the methods of designing China CATV 470MHz frequency synthesis tuner are presented. Two important problems of noise figure and oscillation temperature in UHF band are disscused with satisfactory results.
