High Gain, Linear Driver

GRF4200 is a linear gain block designed for small cell, wireless infrastructure and other high performance applications. It exhibits outstanding linearity, gain and efficiency over 1700 to 2000 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 5 to 40 mA for optimal efficiency and linearity.

GRF4200 requires simple external matching to yield high performance over fractional bandwidths of 10 to 15%.
