Based on the company’s Virtex family of platform FPGAs and XtremeDSP solutions, the digital pre-distortion (DPD) reference design is optimized for Freescale Semiconductor’s RF power LDMOS devices for wireless infrastructure. The DPD reference design can be used to develop LTE, WiMAX, WCDMA and TD-SCDMA multi-carrier systems
This digital pre-distortion technique preconditions the signal entering the amplifier to compensate the non-linear transfer characteristics of the power amplifiers, resulting in a more linear, higher output power radio. Alternatively, the technique allows the system designer to choose a smaller output stage if desired, saving both cost and power.
