Low Noise Amplifier with Bypass 802.11a/n/ac; 4.9 - 6.0 GHz

The GRF2541 is an ultra-low noise amplifier (LNA) with bypass designed for IEEE 802.11a/n/ac/p applications in the 5GHz band (5.1 GHz to 5.925 GHz). The device exhibits outstanding de-embedded noise figure (NF) of 1.0 dB along with a high, flat gain of approximately 17.0 to 17.5 dB over the band. Guerrilla Armor™ technology provides exceptional off-state isolation in the presence of high RF input signal levels in LNA disabled mode. The LNA is operated from a single positive supply of 2.7 to 5.0 V with a selectable Iddq range of 8 to 30 mA. The typical bias condition is 3.3 volts and 15 mA.
