Doherty amplifiers

A Doherty amplifier device comprising:

• a Doherty amplifier comprising:
• a main-power-amplifier having a main-amp-output-terminal;
• a peaking-power-amplifier having a peaking-amp-output-terminal;
• a combining node;
• a main-output-impedance-inverter, wherein the main-output-impedance comprises a CLC-inductor, a first-CLC-capacitor and a second-CLC-capacitor, wherein:
• the CLC-inductor is connected between the main-amp-output-terminal and the combining node;
• the first-CLC-capacitor is connected between the main-amp-output-terminal and a reference terminal;
• and
• the second-CLC-capacitor is connected between the combining node and the reference terminal;
• an autotransformer that comprises a first-end-terminal, a second-end-terminal and an intermediate-terminal, wherein:
• the first-end-terminal is galvanically connected to the combining node;
• the intermediate-terminal is galvanically connected to the peaking-amp-output-terminal;
• and
• the second-end-terminal is connected to the reference terminal
• a shunt-capacitor, wherein the shunt-capacitor has:
• a first plate connected to the first-end-terminal of the autotransformer, and
• a second plate connected to the second-end-terminal of the autotransformer;
• a high-pass-capacitor and a high-pass-inductor, wherein:
• the high-pass-capacitor is connected between (i) the first-end-terminal of the autotransformer, and (ii) the combining node;
• and
• the high-pass-inductor is connected between the combining node and the reference terminal;
• a matching network, wherein the matching network comprises a matching-capacitor and a matching-inductor, wherein the matching-capacitor and the matching-inductor are connected in series between the combining node and the reference terminal;
• an integrated circuit;
• a laminate;
• wherein:
• the autotransformer, the high-pass-capacitor, the shunt-capacitor and the first-CLC-capacitor are provided by the integrated circuit, and
• the high-pass-inductor, the CLC-inductor, the second-CLC-capacitor, the matching-capacitor and the matching-inductor are provided on the laminate.
