RF Power Amplifier Precorrection System

General Description Digital Precorrection (Predistortion) system used to compensate for the non-linearity of an RF power amplifier. Compensates for both Gain and Phase. The design may be used in open-loop configuration or in closed-loop configuration as part of an adaptive precorrection system. Complex LUT stores the inverse (AM-AM) and (AM-PM) characteristics of the Amplifier. Optional choice of programming interfaces (I2C, SPI or UART) may be provided as an extra. Key Design Features - Corrects the PA Gain and Phase responses - 16-bit signed (I/Q) inputs and outputs - 256x32-bit LUT to store inverse PA characteristic - LUT initialized at compile time or modified in-circuit - Suitable for open or closed-loop operation - Operation at Baseband or IF frequencies - Typical improvements of 20dBs in the 'shoulders' - Pipeline latency of only 8 clock cycles - FPGA sample rates of 180 MHz+ Applications - Linearization for Mobile base-stations - Linearization for Digital-TV Broadcasting - Precorrection of any type of digitally modulated   signal where the signal envelope varies and   therefore the instantaneous input power   e.g. UMTS, WCDMA, OFDM etc. View full product datasheet: Details   SKU SKU35 Price: $3000.00 Options   Quantity 1 (this product is downloadable)
