General Description

The SPF5043Z is a high-performance GaAs pHEMT

MMIC LNA designed for operation from 50 MHz to 4000

MHz. The on-chip active bias network provides stable

current over temperature and process threshold voltage

variations.

The SPF5043Z offers ultra-low noise figure and high

linearity performance in a gain block configuration. Its

single-supply operation and integrated matching networks

make

implementation

remarkably

simple.

The

high

maximum input power specification makes it ideal for high

dynamic range receivers.
