General Description

The SC1894 is the Scintera® 3rd generation of RF PA lin-

earizers (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 sup-

port features are accessed through the SC1894’s serial

peripheral interface (SPI) bus.
