Broadband LNA/Linear Driver
Tuning Range: 0.1 to 3.8 GHz

The GRF4002 is a broadband low noise gain block 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 first stage LNA, linear driver or cascaded gain block, GRF4002 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 5.0 V with a selectable Iddq range of 20 to 80 mA for optimal efficiency and linearity. GRF4002 is internally matched to 50 Ω at the input and output ports, needing only external DC blocks and a bias choke on the output.
