SX1701 – Datasheet
Highly linear wideband LNA
Multi-channel, single-ended to differential conversion
GENERAL DESCRIPTION
The SX1701 is an integrated LNA operating over a wide
frequency range from 40 MHz to 2.5 GHz. It is optimized
for high OIP2 and OIP3 with minimum current
consumption. It also performs a single-ended to
differential conversion.
Three independent output channels are available and the
gain of each may be adjusted independently.

... 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 ...
