High Gain, Ultra-LNA with Bypass

802.11ac: 4.9—6.0 GHz

GRF2543 is an ultra-low noise amplifier (LNA) with bypass designed for IEEE 802.11a/n/ac/p applications over 5.1 GHz to 5.925 GHz. The device exhibits outstanding noise figure, linearity and gain to 6 GHz. Note that the reported NF is for the entire evaluation board from SMA to SMA connector.

The LNA is operated from a single positive supply of 2.7 to 5.0 V with typical bias condition of 3.3 volts and 15 mA.

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