Claim 9:
10. The wireless device according to claim 9, wherein the plurality of mixers comprise:
a mixer that uses a first local signal to up-convert the frequency of the in-phase signal processed by the corresponding phase switcher and variable amplifier;
a mixer that uses the first local signal to up-convert the frequency of the quadrature signal processed by the corresponding phase switcher and variable amplifier;
a mixer that uses a second local signal to up-convert the frequency of the in-phase signal processed by the corresponding phase switcher and variable amplifier, the second local signal being rotated 90º in phase relative to the first local signal; and
a mixer that uses the second local signal to up-convert the frequency of the quadrature signal processed by the corresponding phase switcher and variable amplifier.
