The GRF2501 is an ultra-low noise amplifier (LNA) de-signed for IEEE 802.11a/n/ac/p applications (5.1 GHz to 5.925 GHz). Over this band, the device exhibits out-standing de-embedded noise figure (NF) of 0.80 dB along with excellent gain flatness. The high gain, superi-or 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. GRF2501 is internally matched to 50 Ω at the input and output ports.
