Aspects of a method and system for efficient transmission and reception of RF energy in MIMO systems using polar modulation and direct digital frequency synthesis are provided. A plurality of carrier signals in a MIMO system may be polar modulated utilizing polar modulation. One or more direct digital frequency synthesizer may be utilized to phase modulate the plurality of carrier signals. The direct digital frequency synthesizer may be modulated utilizing a single reference clock. The clock may be a single fixed-frequency reference clock. The plurality of carrier signals may be amplitude modulated by controlling a gain of a power amplifier.
