The RF2371 is a general purpose, low-cost, high perfor-
mance low noise amplifier designed for operation from a

down mode, providing a known gain step. The RF2371 is
available in a small industry-standard SOT23-8 surface
mount package, enabling compact designs which con-

serve board space. The design features a highly accurate
PTAT (Proportional To Absolute Temperature) biasing
scheme using bandgap cells.
