摘要：A quadrature modulator includes a first switched capacitor power amplifier thatamplifies a first high-frequency signal having a first phase, a second switched capacitorpower amplifier that amplifies a second high-frequency signal having a second phasedifferent from the first phase, a first combiner which includes at least one pair of winding
wires that are magnetically coupled to each other, one winding wire in one pair beingdisposed on a primary side to which the amplified first high-frequency signal and theamplified second high-frequency signal are separately input and the other winding wire inthe one pair being disposed on a secondary side, the first combiner combining the inputamplified first high-frequency signal and the input amplified second high-frequency signalto generate a quadrature modulation signal from the secondary side, a first inductordisposed between the first switched capacitor power amplifier and the primary side ofthe first combiner, and a second inductor disposed between the second switchedcapacitor power amplifier and the primary side of the first combiner.
