The GRF4003 is a broadband low noise gain block designed for small cell, wireless infrastructure and other high-performance applications. It exhibits outstanding broadband noise figure (NF), linearity and return losses over 0.01 to 3.8 GHz with a single match. Configured as a first stage LNA, linear driver or cascaded gain block, GRF4003 offers high levels of reuse both within a design and across platforms. The device is typically operated from a supply voltage (VDD) of 1.8 to 5.5 volts with a selectable IDDQ range of 30 to 120 mA for optimal efficiency and linearity.The GRF4003 is internally matched to 50 Ω at the input and output ports, needing only external DC blocks and a bias choke on the output.
