Adaptive RF Power Amplifier Linearizer

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.
