Broadband LNA/Linear Driver

Tuning Range: 0.1 to 3.8 GHz

The GRF4003 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, GRF4003 offers high levels of reuse both within a design and across platforms. The device is operated from a supply voltage of 1.8 V to 5.5 V with a selectable Iddq range of 30 to 100 mA for optimal efficiency and linearity.

GRF4003 is internally matched to 50 Ω at the input and output ports, needing only external DC blocks and a bias choke on the output.
