Patent number: 10419046Abstract: A quadrature transmitter includes a first and second matched transmitter path. Each transmitter path receives respective sets of quadrature baseband signals. At least one local oscillator port receives respective sets of quadrature LO signals. Mixer stage(s) respectively multiply the sets of quadrature baseband signals with the respective sets of quadrature LO signals to produce a respective output radio frequency signal. A combiner combines the output RF signals. The first set of quadrature signals is a substantially 45° phase shifted version of the second set of quadrature signals; and the first set of quadrature LO signals is a reverse substantially 45° phase shifted version of the second set of quadrature LO signals. A baseband error correction circuit corrects a phase error between the quadrature baseband signals at baseband and a LO error correction circuit corrects a phase error between the quadrature baseband signals at a LO frequency.Type: GrantFiled: June 7, 2018Date of Patent: September 17, 2019Assignee: MediaTek Singapore Pte.
