Ultra-Low Noise Amplifier
Tuning Range: 0.7 to 3.8 GHz

GRF2051 is an ultra-low noise amplifier designed for wireless infrastructure and other high performance RF applications requiring the absolute lowest possible NF, high gain and outstanding linearity. Broadband external matches deliver outstanding RF performance over 0.7 to 3.8 GHz.

Configured as a first stage LNA, linear driver or cascaded gain block, the GRF2051 flexible biasing capability offers high levels of reuse both within a design and across platforms. For higher gain applications from 1.5 GHz up to 4.5 GHz, the pin compatible GRF2052 should be used.
