GRF4004
Preliminary
Broadband LNA/Linear Driver
0.1 – 3.8 GHz
Package: 1.5 x 1.5 mm DFN-6
Product Description
The GRF4004 is a broadband low noise gain block designed
for small cell, wireless infrastructure and other high
performance applications. Typical external matches exhibit
outstanding broadband NF, linearity and return losses over
0.4 to 1.0 GHz and 1.7 to 2.7 GHz and the device can be
tuned to deliver excellent performance over 0.1 to 3.8 GHz.
Configured as a first stage LNA, linear driver or cascaded gain
block, GRF4004 offers high levels of reuse both within a
design and across platforms. The device is operated from a
supply voltage (Vdd) of 1.8 to 5.5 V with a selectable Iddq
range of 30 to 150 mA for optimal efficiency and linearity.
Consult with the GRF applications engineering team for
custom tuning/evaluation board data and device s-
parameters.
