    摘要： A quadrature modulator has first to fourth transistors, a first node, a second node, and a first output node. A non-inversion in-phase analog signal, an inversion in-phase analog signal, a non-inversion quadrature analog signal, and an inversion quadrature analog signal are supplied to input electrodes of the first to fourth transistors, respectively. Control electrodes of the first to fourth transistors respond to a non-inversion in-phase RF signal, an inversion in-phase RF signal, a non-inversion quadrature RF signal, and an inversion quadrature RF signal, respectively. Output electrodes of the first and second transistors are coupled to the first node, and output electrodes of the third and fourth transistors are coupled to the second node. A first high-pass filter is coupled between the first node and the first output node, and a second high-pass filter is coupled between the second node and the first output node.
