A method for operating a multiple standard transmitter, said method comprising the steps of: providing a multiple standard transmitter, including selectable components in a plurality of transmit architectures that allow the multiple standard transmitter to communicate using a desired transmission standard, characterized by a constant envelope output provided by a software defined transmit architecture, the constant envelope output comprising only a phase modulated signal formed by a first transmit chain, a non-constant envelope output provided by the software defined transmit architecture, the non-constant envelope output comprising both a phase modulated signal and an amplitude modulated signal formed by a second transmit chain, the constant envelope output and the non-constant envelope output combined in an out-phasing process such that the phase difference of two signals that contain only a phase modulated component develop a signal that includes both a phase modulated component and an amplitude modulated component; and enabling one of the plurality of transmit architectures to transmit a communication signal having the phase modulated component and the amplitude modulated component. providing a multiple standard transmitter, including selectable components in a plurality of transmit architectures that allow the multiple standard transmitter to communicate using a desired transmission standard, characterized by a constant envelope output provided by a software defined transmit architecture, the constant envelope output comprising only a phase modulated signal formed by a first transmit chain, a non-constant envelope output provided by the software defined transmit architecture, the non-constant envelope output comprising both a phase modulated signal and an amplitude modulated signal formed by a second transmit chain, the constant envelope output and the non-constant envelope output combined in an out-phasing process such that the phase difference of two signals that contain only a phase modulated component develop a signal that includes both a phase modulated component and an amplitude modulated component; and selectable components in a plurality of transmit architectures that allow the multiple standard transmitter to communicate using a desired transmission standard, characterized by a constant envelope output provided by a software defined transmit architecture, the constant envelope output comprising only a phase modulated signal formed by a first transmit chain, a non-constant envelope output provided by the software defined transmit architecture, the non-constant envelope output comprising both a phase modulated signal and an amplitude modulated signal formed by a second transmit chain, the constant envelope output and the non-constant envelope output combined in an out-phasing process such that the phase difference of two signals that contain only a phase modulated component develop a signal that includes both a phase modulated component and an amplitude modulated component; and enabling one of the plurality of transmit architectures to transmit a communication signal having the phase modulated component and the amplitude modulated component.
