A communications device (10, 10') may include an encoder (11, 11') generating digital baseband In-phase (I) and Quadrature (Q) signals, a processor (12, 12') coupled to the encoder and extracting an envelope characteristic from the digital baseband I and Q signals based upon a bandwidth of the digital baseband I and Q signals. A power amplifier (18, 18') may be coupled downstream from the processor and may generate an amplified I and Q signal based upon the envelope characteristic.
