Low Noise Amplifier with Bypass & Guerrilla Armor™; 0.4 – 2.7 GHz

GRF4042 is a low noise amplifier (LNA) with low loss bypass designed for high performance applications up to 2.7 GHz. Guerrilla Armor™ technology provides exceptional off-state isolation in the presence of high RF input signal levels in LNA disabled mode.

With integrated matching, the device achieves outstanding noise figure (NF), high gain and high linearity over 400-2700 MHz using as few as three external components. The data sheet also provides narrow band matches covering 700-960 MHz and 1710-2170 MHz for applications needing enhanced return loss.

The LNA is operated from a single positive supply of 1.8 to 5.0 V with a selectable Iddq range of 15 to 90 mA.
