SX1701A – Datasheet
Highly linear wideband LNA
Single-channel, single-ended to differential conversion
GENERAL DESCRIPTION
The SX1701A 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 with 3 selectable gains.
