Abstract:
1. An I/Q modulator device comprising: a first modulator component comprising at least one EXOR gate to combine an in-phase component of a local oscillator signal with a signal representing a sign of an in-phase component of a baseband signal to generate an output signal of the first modulator component; a second modulator component comprising at least one additional EXOR gate to combine a quadrature component of a local oscillator signal with a signal representing a sign of a quadrature component of a baseband signal to generate an output signal of the second modulator component; a third modulator component configured to combine the output signal of the first modulator component with a signal representing a magnitude of the in-phase component of the baseband signal to generate an output signal of the third modulator component; a fourth modulator component configured to combine the output signal of the second modulator component with a signal representing a magnitude of the quadrature component of the baseband signal to generate an output signal of the fourth modulator component; and a fifth modulator component configured to combine the output signals of the third and fourth modulator components to generate an output signal of the I/Q modulator.
