摘　　要：双路同步下混频器是双路同步接收机的一个核心部件,讨论了一种基于MAX2116芯片设计的数控射频双路同步下混频器。其硬件电路简单,可根据设计要求,通过I2C总线迅速灵活地完成本振频率、通道增益和带宽等参数的设置,且具有性能在线优化功能。实际使用结果表明该双路同步下混频器调试方便、性能良好。The twin channel synchronous down--mixer is the key part of the twin channel synchronous receiver. A kind of numerically controlled twin channel synchronous down--mixer based on MAX2116 chip is discussed. The main problems of its design are described in detail Such mixer is simple in circuit with on-line performance optimizing function, its parameters such as local osillating frequency, channel gains and bandwidth can be set by I^2 C bus flexibly and rapidly according to the design reqirements. The results of its application have showed that such mixer is perfect in performance and convienent in debugging.
