1. A method for selecting a modulation architecture, comprising:

  • receiving a control input signal to select a modulation architecture;

    when a first modulation architecture is selected based on said control input signal;

    applying a time varying and substantially known baseband bias control signal to a bias input of a power amplification module; and

    applying a time varying and substantially known baseband modulation envelope signal to an input of said power amplification module; and

    when a second modulation architecture is selected based on said control input signal;

    applying said time varying and substantially known baseband modulation envelope signal to said bias input of said power amplification module; and

    applying said time varying and substantially known baseband bias control signal to said input of said power amplification module.
