摘要
本文就ＭＭＤＳ多路微波分配系统基带合成器的一种方案进行了详细论述。给出了所研制的基带合成器具体电路，整个电路采用了二片集成电路块、外圆元件少，调试方便。作者采用共基电路作三路音频副载波混合电路，并对其提出了〔Ｙ〕参数分析法，导出了计算公式，对具体参数给出了计算结果，并进行了分析。
This article discussed a plan about MMDS Bassband Synthesizer and provided its particular circuit in detail.In this circuit we used two special IC chips,so it has a few peripheral components and made the adjusting convenient.After being used in practice,its performance is stable and its quallity is fine. \ \ We used common base circuit as mix circuit of 3-Audio subcarrior,provided Y parameter analysis and deduced its formular.In addition,we listed and discussed the result of special parameter.Simultaneously,we discussed some concrete problem in its design process
