摘要： The invention is a radio transmitter and a method for transforming digital amplitude as well as phase or frequency modulation information into analog signals for controlling analog amplifier circuitry. The method includes providing first and second digital signals representing phase angle; converting the signals into analog signals; mixing the analog signals with oscillator signals to obtain an analog, modulated signal; providing a third digital signal corresponding to amplitude; converting this signal into an analog signal; and feeding the analog, modulated signal and said analog signal to the analog amplifier circuitry.
