Broadband LNA/Linear Driver 0.1 – 3.8 GHz

The GRF4005 is a broadband low noise gain block designed for small cell, wireless infrastructure and other high performance applications. The device exhibits outstanding broadband NF, linearity and return losses over 1.7 to 2.7 GHz with a single match and it 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, GRF4005 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 50 to 200 mA for optimal efficiency and linearity.

Consult with the GRF applications engineering team for application notes and custom tuning/evaluation board data.
