SA9500/SA9502是专为CDMA/AMPS设计的前端接收下变频器 ,它包括三个独立的混频器 ,能达到蜂窝和PCS波段所要求的最大失真抑制 ,且耗流低、线性度高。它还可工作于休眠状态。文中从应用角度出发阐述了在电路中实现其功能的方法以及应用时需要注意的问题
The SA9500 / SA9502 is a front-end receive downconverter designed for CDMA / AMPS that includes three independent mixers to achieve the maximum distortion reduction required for cellular and PCS bands with low current consumption and high linearity. It can also work in hibernation. From the application point of view, this paper expounds the method of realizing its function in the circuit and the problems needing attention when applying
