The SC1869 is part of the 2nd generation RF PA linearizer (RFPAL) family providing increased ACLR correction over the previous generation as well as support for EVDO, TD-SCDMA, WiMAX, HSDPA, LTE and TD-LTE waveforms. The SC1869 is a fully-adaptive, RFin/RFout predistortion linearization solution that precisely compensates RF power amplifier (PA) nonlinearities including AM/AM and AM/PM distortion, spectral regrowth, memory effects and other system level impairments.

The SC1869 is a complete system-on-chip (SoC) solution optimized for Class A/AB RF power amplifiers operating at an average power level of 500mW to 10W (RMS).

Note: All SCxx parts are RoHS. An appended “E” at the end of the part number indicates 7” Tape and Reel. No appended letter or a “K” at the end of the part number indicates bulk.
