... SIMPLIFIED BLOCK DIAGRAM The simplified block diagram of the SX1701 is illustrated below in Figure 1. The amplifier comprises two main stages. The first stage is common to all channels and performs the single-ended to differential conversion. The second stage, duplicated for all channels, is implemented as two cascaded stages and performs independently the gain control for each channel ...
