High Linearity Gain Block
Tuning Range: 0.05 to 3.8 GHz

The GRF2012 is a broadband gain block with low noise figure and industry leading linearity designed for small cell, wireless infrastructure and other high performance applications. It exhibits outstanding broadband NF, linearity and return losses over 700 to 3800 MHz with a single match.

Configured as a linear driver or cascaded gain block, GRF2012 offers high levels of reuse both within a design and across platforms. The device is operated from a supply voltage of 2.7 to 5.0 V with a selectable Iddq range of 30 to 120 mA for optimal efficiency and linearity.

GRF2012 is internally matched to 50 Ω at the input and output ports, needing only external DC blocks and a bias choke on the output.
