Abstract:
A method for using a translation loop modulator and power amplifier in a phase and amplitude modulated transmission environment, comprising the steps of:providing a phase modulated signal to a translation loop, the translation loop providing a frequency specific phase modulated signal, the translation loop also having a phase locked loop; providing said frequency specific phase modulated signal to a power amplifier; providing an amplitude modulated signal to the power amplifier using a variable gain element associated with a control loop; detecting a portion of an output of the translation loop and a portion of an output power of the power amplifier; applying the detected output portion of the translation loop to an input of the translation loop during a first time period; and applying the detected output power portion of the power amplifier to the input of the translation loop modulator during a second time period, wherein the detected output power portion of the power amplifier that is supplied during the second time period is a substantially constant power level signal containing only phase information.
