Abstract:
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.

Claim (Index 20):
A method for a transmitter that comprises a first transmitter path and a second transmitter path that are matched, the method comprising:\n receiving first sets of quadrature baseband signals at the first transmitter path; receiving second sets of quadrature baseband signals at the second transmitter path; correcting a phase error between the first or second sets of quadrature baseband signals at baseband by a baseband error correction circuit; generating respective first and second sets of quadrature LO signals; correcting a phase error between the first or second sets of quadrature baseband signals at a LO frequency by a LO error correction circuit; multiplying the first and second sets of quadrature baseband signals with the respective first or second sets of quadrature LO signals to produce a respective output radio frequency, RF, signal; and combining the output radio frequency signals of the first transmitter path and the second transmitter path; wherein:\n the first set of quadrature baseband signals is a substantially 45\u00b0 phase shifted version of the second set of quadrature baseband signals; and \n the first set of quadrature LO signals is a reverse substantially 45\u00b0 phase shifted version of the second set of quadrature LO signals.
