High Gain, Ultra-LNA

GRF2501W 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 de-embedded noise figure (NF) of 0.80 dB along with excellent gain flatness. 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 2.7 to 5.0 V with a typical bias condition of 3.3 V and 15 mA. GRF2501W is internally matched to 50 Ω at the input and output ports.

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