SC1869

SC1869 Adaptive RF Power Amplifier Linearizer General Description Features The SC1869 is part of Scintera’s 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. RFin/RFout PA Linearizer SoC in Standard CMOS Fully Adaptive Compensation Low Power Consumption: o Duty-Cycled (9%) Feedback: 420mW o Full Adaptation: 1.06W Frequency Range: 698MHz to 2800MHz Input Signal Bandwidth: Up to 20MHz Up to 28dB ACLR and 38dB IMD Improvement* Packaged in 9mm x 9mm QFN Package Operating Case Temperature: -40°C to +100°C The SC1869 substantially increases power amplifier Fully RoHS Compliant, Green Materials efficiency by reducing out-of-band energy. The Pin Compatible with SC1887 and SC1869 SC1869 is a complete system-on-chip (SoC) solution optimized for Class A/AB RF power amplifiers Benefits operating at an average power level of 500mW to 10W (RMS). The SC1869 measures the feedback signal from the power amplifier output, and optimizes the correction function by minimizing distortion. SC1869 correction function is generated using RFdomain analog signal processing allo...
