摘要： An apparatus and methods for a baseband modulator configured to code amplitude signals into pulse width modulated time signals comprising at least two amplitude levels is disclosed. A pulse width modulator can receive a component signal of a baseband complex signal and generate a discrete-time pulse width modulated signal. This signal can be converted to a continuous time signal, such as a pulse-width modulated time signal and can be shifted to a carrier signal corresponding respectively to the component signal by a switch. Bursts sequences are generated to an input of a switched amplifier for driving operation of the amplifier therein.

摘要： A power amplifier includes a baseband modulator configured to receive a baseband amplitude component and generate a baseband modulated pulse string, an oscillator configured to receive a baseband phase component and generate phase modulated complex carrier signals, a complex up-converter configured to receive and mix the baseband modulated pulse string with the phase modulated complex carrier signals into mixed product signals, and two or more switched mode power amplifiers coupled to the complex up-converter, configured to amplify and switch the mixed product signals at the carrier frequency. The power amplifier further comprises complex filters individually coupled to one of the switch mode power amplifiers, configured to suppress image components in the amplified and switched mixed product signals, and a power combiner coupled to the two or more complex filters, configured to combine the real component of the complex filtered and amplified mixed product signals to generate an RF transmission signal.

摘要： A signal is modulated by generating a pulse-width modulation signal and applying the pulse-width modulation signal to an input of a switched-mode amplifier. An output of the amplifier is coupled to a filter operable to impart either differential mode oscillations or common mode oscillations at the amplifier output based on the duty cycle of the pulse-width modulation signal. The duty cycle of the pulse-width modulation signal is varied to impart amplitude modulations at the amplifier output.
