Signal generation apparatus for frequency conversion in communication system |
摘要 |
A signal generation apparatus includes a signal generation portion and a phase compensator. The phase compensator generates a phase error control signal that maintains a phase difference between the in-phase and quadrature-phase signals generated by the signal generation portion. The phase compensator includes an offset compensator and a delay compensator. The offset compensator is set to compensate for an offset voltage through the phase compensator. The delay compensator is set to compensate for a difference of delays through paths for the in-phase and quadrature-phase signals within the phase compensator.
