The SC1905 is a pin-compatible upgrade of the popular SC1894 RF PA linearizer (RFPAL) supporting signal bandwidths up to 100MHz. The SC1905 is a fully adaptive, RFin/RFout predistortion linearization solution optimized for a wide range of amplifiers, power levels, and communication protocols. The SC1905 uses the PA output and input signals to adaptively generate an optimized correction function in order to minimize the PA’s self-generated distortion and impairments. Using RF-domain analog signal processing enables the SC1905 to operate over wide-signal bandwidths and consume very low power.Design support features are accessed through the SC1905’s serial peripheral interface (SPI) bus.APPLICATIONS4G and 5G Cellular InfrastructureAmplifier: Class A/AB and DohertyAny Application Requiring PA LinearizationBTS Amplifiers, RRH, Booster Amplifiers, Repeaters, Small Cells, Microcells, Picocells, DAS, AAS, and MIMO SystemsPA Process: LDMOS, GaN, GaAs, and InGaPSingle/Multicarrier, Multistandard: WCDMA, LTE, and TD-LTEWide Range of PAs and Output Power
