| Abstract: | 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. |
