The GRF5124 from Guerrilla RF is a Two-Stage Driver Amplifier that operates from 1.8 to 5 GHz. It provides 40.2 dB of gain with a noise figure of 1.6 dB and has an output P1dB of up to 23.3 dBm. This amplifier has flexible biasing that provides latitude for linearity optimization, requires a DC supply of 3.3 or 5 V, and consumes less than 109 mA of current. It is available in a compact QFN-16 package that measures 3 x 3 mm and is ideal for linear driver/pre-driver amplifiers, 5G Sub-6 GHz massive MIMO base stations, small cells and cellular repeaters, millimeter wave IF stages, and high-performance RF infrastructure applications.
