Circuitry (314, 316, 318, 320) separates a modulation signal into digital sign (S4, S7) and magnitude (S5, S6) signal components. The digital magnitude signal is converted to an analog magnitude signal. The analog magnitude signal is then mixed with an in-phase (IC) or quadrature (QC) carrier signal under the influence of the digital sign signal (S4, S7) and routed to a driver output stage (332). |
