RF Predistortion Ics
Analog Devices’ RF power linearizer (RFPAL) devices feature a programmable analog signal processing architecture that effectively combines digital programmability with the simplicity, small size, and low power consumption of analog circuit design. The benefit provided by this architecture is a predistortion linearization solution with very low power consumption, wide bandwidth performance, and a compact system footprint. These products have achieved broad acceptance in the cellular infrastructure and microwave point-to-point markets. Wide field deployment has proven these RFPAL devices to be robust solutions capable of dramatically increasing system efficiency and reducing costs in existing applications. They are now also enabling novel high performance, cost sensitive, and very compact 4G cellular small cell designs used in heterogeneous network deployments.
