Broadband Linear Driver

GRF4100 is a broadband linear gain block designed for small cell, wireless infrastructure and other high performance applications. It exhibits outstanding broadband gain and linearity over 200 to 2700 MHz with a single match.

The device is operated from a supply voltage (VCC) of 2.7 to 5.0 V with a selectable ICCQ range of 20 to 40 mA for optimal efficiency and linearity.

GRF4100 is internally matched to 50 ω at the input and output ports, needing only external DC blocks and a bias choke on the output.

Consult with the GRF applications engineering team for custom tuning/evaluation board data and device s-parameters.
