Full output matching apparatus of the microwave doherty amplifier

The invention in a very high frequency Doherty amplifier which relates to the output matching unit for high frequency Doherty amplifier, by connecting a quarter-wave transformer to the final output of a carrier amplifier and a peaking amplifier connected in parallel to occur a Doherty operation, the carrier amplifier and the peaking amplifier and a load matching network form a high-frequency output matching network coupled to the output, the load is the phase-tuning component coupled to the rear end of the matching circuit, not changing the matching in the high-output and to maintain the characteristics of the low output, the efficiency and linearity optimized in accordance with the phase so there is an advantage that can be adjusted to match.
