LNA with Bypass

Tuning Range: 0.4 to 5.0 GHz

GRF2243 is a low noise amplifier (LNA) with low loss by-pass which requires only a single control input. It is designed for high performance applications up to 5.0 GHz.

With minimal external matching, the device achieves outstanding noise figure (NF), high gain and efficient linearity. The LNA is operated from a single positive supply of 2.7 to 5.0 V with a selectable Iddq range of 8 to 25 mA.
