摘要： The present invention relates to a method for controlling an amplifier unit having at least one drive signal input connection 1, at least one power supply voltage input connection 2 and an output connection 4. The amplifier unit comprises at least one amplifier, and the method comprises the steps of: feeding each amplifier by a drive signal from said at least one drive signal input connection 1, and feeding each amplifier by a power supply voltage from said at least one power supply voltage input connection, whereby said amplifier unit has defined output characteristics at the output connection 4 and a predetermined power supply voltage at a maximum RF output power for a RF signal. The method further comprises the steps of: operating at least one amplifier with RF output voltage characteristics to obtain a reduced shunt loss, compared to a reference shunt loss, at the output connection 4. The reference shunt loss is obtained when operating each amplifier as a class B amplifier having the defined output characteristics at the output connection 4 and the predetermined power supply voltage at a maximum RF output power for the RF signal, and modulating the power supply voltage to each amplifier to reduce excessive voltage drop over the amplifier.

摘要： To generate a high-power modulated radio frequency signal SOUT from an input low or medium frequency information signal SIN, the information signal is pulse-shaped in a quantifier to form a digital signal SD having discrete signal values. The digital signal is processed in a switching unit comprising switches for each signal value, in radio frequency wave generators for each switch generating carrier waves of radio frequency, and in control circuits for each switch to control the opening and closing thereof. When a switch is closed, its associated generator is connected to the output line of the switching unit, and when it is opened, the generator is disconnected therefrom. In the switching unit, a switched radio frequency signal SSW carrying the information of the input signal is formed by opening and closing the switches when the digital signal adopts or does not adopt, respectively, the signal value associated with the respective switch. The switching is thus controlled by the signal values of the digital signal. The switched signal on the output line of the switching unit is filtered by a filter for achieving the high-power, modulated, radio frequency signal SOUT.

摘要： A power amplifier comprises a level-discretization modulator (210) and a mixing and amplifying stage (225), in combination with a properly designed negative feedback path. The feedback path forms an error compensation loop together with a properly selected forward path. The forward path includes at least the mixing and amplifying stage (225), which provides frequency up-conversion to the radio frequency band and switch-based amplification. The negative feedback path includes a down-conversion mixer (280) for down-conversion to the initial frequency band, and compensates for distortion caused by components of the forward path.
