GRF4042
LNA w/Bypass & Guerrilla
Armor™: 0.4 to 2.7 GHz
Product Description
GRF4042 is a low noise amplifier (LNA) with low loss by-
pass designed for high performance applications up to
2.7 GHz. Guerrilla Armor™ technology provides excep-
tional off-state isolation in the presence of high RF input
signal levels in LNA disabled mode.
Features
Reference: 5V/70mA/1.9 GHz
•
Bypass + Guerrilla Armor™
With integrated matching, the device achieves outstand-
ing noise figure (NF), high gain and high linearity over
400-2700 MHz using as few as three external compo-
nents. The data sheet also provides narrow band match-
es covering 700-960 MHz and 1710-2170 MHz for ap-
plications needing enhanced return loss.

•
EVB NF: 1.0 dB
Gain: 16.0 dB
Bypass Gain: -1.5 dB
OIP3: 36.3 dBm
OP1dB: 22.0 dBm
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.
Consult with the GRF applications engineering team for
custom tuning/evaluation board data and device s-
parameters.
