High Gain, Ultra-LNA 802.11ac: 4.9—6.0 GHz

The GRF2101 is an ultra-low noise amplifier (LNA) designed for IEEE 802.11a/n/ac/p applications (5.1 GHz to 5.925 GHz). Over this band, the device exhibits outstanding evaluation board noise figure (NF) of 0.75 dB. The high gain, superior NF and directivity of its design allows designers to create receiver architectures with outstanding cascaded NF and unconditional stability.

The LNA is operated from a single positive supply of 2.8 to 5.0 V with a typical bias condition of 3.3 V and 15 mA.

Consult with the GRF applications engineering team for application notes and custom tuning/evaluation board data.
