ABSTRACT:
A dual modulation transmitter apparatus (100) includes first (134), second (136), and third (132) signal paths. The first signal path includes a polar modulator (120) coupled to a data input (115). The second signal path includes a quadrature modulator (122) coupled to the data input. The third signal path is coupled to an antenna (142) and includes a switch (128) configured to couple the third signal path to the first signal path under a first condition and to couple the third signal path to the second signal path under a second condition. Thus, the transmitter apparatus enjoys the best of both worlds, since it utilizes quadrature or polar modulation in the most appropriate circumstances.
