Ultra-High Gain LNA 0.4 to 2.7 GHz

The GRF2133 is a broadband linear gain block featuring ultra-high gain and sub 0.8 dB noise figure for small cell, cellular booster, wireless infrastructure and other high performance applications.

Configured as a linear driver, LNA or cascaded gain block, it offers high levels of reuse both within a design and across platforms. The device is operated from a supply voltage of 1.8 to 5.0 V with a selectable Iddq range of 30 to 160 mA for optimal efficiency and linearity.
