14.1 English
  • Algorithm
    • DPD correction with up to 40 dB of adjacent channel leakage ratio (ACLR) improvement
    • Handles long term memory effects seen with Gallium Nitride (GaN) Amplifiers to meet stringent FCC and 3GPP MIMO requirements
  • Physical Configuration Parameters
    • Selection of phase options for datapath implementation allowing a resource/sample rate trade-off
    • Selection of one, two, four, six or eight transmit antennas
    • Multiple filter and capture depth options, delivers a highly adaptable solution which enables cost optimized solution for macro Base Stations, massive MIMO 5G RRH, micro Remote Radio Head (RRH), Distributed Antenna System (DAS), and low power PA applications, independent control of filter memory and capture memory depth and acceleration levels allowing for resource versus performance trade-off.
  • Software
    • Support for SMP mode under Linux Operating System. Currently, only AMD SoCs can host DPD IP, as a PS running Linux is mandatory
    • C API for Host Processor
    • DFE Reference Design included
