GRF2243

LNA with Bypass
Tuning Range: 0.1 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.

Consult with the GRF applications engineering team for custom tuning/evaluation board data and device s-parameters.
