SC1894 225MHz to 3800MHz RF Power Amplifier Linearizer (RFPAL) General Description 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.
