Crest Factor Reduction-CFR


FlexCFR is a field-proven, high-flexibility Crest Factor Reduction solution that enables RF transmitter systems to use power amplifiers (PA) more efficiently. Systems4Silicon supplies all IP for a complete CFR sub-system that is user customizable and independent of the target device.


Features and Benefits


 

  • Improves amplifier efficiency by increasing the average transmit power relative to the PA bias power.
  • Dynamically re-configurable for single/multi-carrier or multi-standard operation.
  • Reduces amplifier costs by enabling the use of power transistors with lower peak-power handling.
  • Supports systems requiring CFR sample rates greater than the FPGA fabric maximum attainable clock rate.
