LNA/Driver with Bypass
Tuning Range: 0.1 to 6.0 GHz

GRF4142 is a low noise amplifier (LNA) with low loss bypass which requires only a single control input. It is designed for high performance applications up to 6.0 GHz.

With minimal external matching, the device achieves outstanding noise figure (NF), high gain and high linearity. The LNA is operated from a single positive supply of 1.8 to 5.0 V with a selectable Iddq range of 15 to 80 mA.
