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 14):
A communication unit comprising a quadrature transmitter that comprises:\n a first transmitter path and a second transmitter path that are matched and wherein each transmitter path comprises:\n at least one input arranged to receive respective first or second sets of quadrature baseband signals; \n at least one local oscillator, LO, port configured to receive respective first and second sets of quadrature LO signals; and \n at least one mixer stage coupled to the at least one input and configured to respectively multiply the 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 \n a combiner configured to combine the output radio frequency signals of the first transmitter path and the second transmitter path; \n 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; and \n wherein at least one of the first transmitter path and second transmitter path comprises a baseband error correction circuit configured to correct a phase error between the first or second sets of quadrature baseband signals at baseband and a LO error correction circuit configured to correct a phase error between the first or second sets of quadrature baseband signals at a LO frequency.
