Part Details

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

The GRF4014 is a broadband low noise gain block de- signed for small cell, wireless infrastructure and other high performance applications. With simple external matching, it exhibits outstanding broadband NF, linearity and return losses over wide fractional bandwidths with a single match.

Configured as a first stage LNA, linear driver or cascaded gain block, GRF4014 offers high levels of reuse both within a design and across platforms. The device is operated from a supply voltage (VDD) of 3.0 to 8.0V. IDDQ can be adjusted over a wide range for optimal efficiency and linearity.

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