The SC1894 is the Scintera® 3rd generation of RF PA linearizers （RFPAL™） that provide improved correction and functionality over the previous generations. The SC1894 is a fully adaptive， RFin/RFout predistortion linearization solution optimized for a wide range of amplifiers， power levels， and communication protocols. The SC1894 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 SC1894 to operate over wide-signal bandwidths and consume very low power. The SC1894 goes beyond linearization and provides accurate RF power measurement of RFIN and RFFB. Design support features including spectral monitoring and ACLR alarm are also available. These design support features are accessed through the SC1894’s serial peripheral interface （SPI） bus.
