Guerrilla RF GRF400x Broadband LNA/Linear Drivers

Guerrilla RF GRF400x Broadband LNA/Linear Drivers are broadband low noise gain blocks designed for small cells, wireless infrastructures, and other high-performance applications. The GRF400x exhibits outstanding broadband NF, linearity, and return losses with a single match. The Guerrilla GRF400x offers high levels of reuse both within a design and across platforms and is configured as first-stage LNAs, linear drivers, or cascaded gain blocks. These devices are operated from a supply voltage of 1.8 to 5.0V with a selectable Iddq range for optimal efficiency and linearity.
