| 摘要 |
An amplifier circuit comprising a carrier amplifier (24) producing a carrier amplifier output signal, a peaking amplifier (26) coupled to the carrier amplifier (24) in a Doherty configuration, and a combination circuit responsive to the carrier amplifier (24) and the peaking amplifier (26). The peaking amplifier (26) is voltage-biased to produce an adjusted intermodulation product signal. The combination circuit (35) combines the adjusted modulation product signal with the carrier amplifier output signal to produce a substantially linearized amplifier circuit output signal.
