  • Predistortion of amplifier input signals
    Patent number: 8577311
    Abstract: Described herein are devices, methods, and techniques related to predistortion of amplifier signals based on an operating condition. Predistortion techniques are described that mitigate or eliminate the effects of variable operating conditions, including nonlinear effects, on amplified signals. Nonlinearities may be mitigated by compensating at a baseband signal prior to amplification, generally using scaling and a static characteristic that is valid for a broad range of operating conditions.
    Type: Grant
