A wideband linear amplification system amplifies an input signal to produce an amplified output signal. An envelope detector determines an envelope detector signal based on the input signal. An amplifier bias controller produces multiple control signals based on the envelope detector signal. A predistortion...http://www.google.es/patents/US6600369?utm_source=gb-gplus-sharePatente US6600369 - Wideband linear amplifier with predistortion error correction
