Patent ID: 7474150

Claim:
An amplifier, comprising: a first amplifier configured to receive a wideband input signal having a carrier signal and output a first amplified signal, the first amplifier introducing first CTB distortions of the carrier signal into the first amplified signal; a first phase filter coupled to said first amplifier so as to receive said first amplified signal as an input, said first phase filter configured to output a first phase shifted signal; a second amplifier coupled to said first phase filter so as to receive said first phase shifted signal and to output a second amplified signal, the second amplifier introducing second CTB distortions of the carrier signal; and the first phase filter configured to shift a phase of the first amplified signal to an extent that substantially reduces accumulation of amplitudes of the CTB distortions produced by the first and second amplifiers while causing power of the CTB distortions produced by the first and second amplifiers to substantially accumulate.
