    Abstract: A peaking amplifier is disclosed. The peaking amplifier includes a driver stage, a final stage, and an interstage matching network. The driver stage has a load impedance and is configured to generate a driver output based on an input signal. The final stage has a final stage input impedance and is configured to generate a peaking output based on the driver output. The interstage matching network is coupled to the driver stage and the final stage. The interstage matching network is configured to transform the final stage input impedance to the load impedance for the driver stage when the peaking amplifier is ON and to provide a short to an input of the final stage when the peaking amplifier is in an OFF state.

    Abstract: The present disclosure relates to a low-complexity transmitter architecture that drives phase modulators with digital signals to generate a pulse width modulated (PWM) signal that is transmitted by an antenna. In some embodiments, the system has a pre-processing element that generates first and second digital control signals from a digital baseband signal. A first phase modulation component introduces a first phase shift into a first local oscillator signal based upon the first control signal and generates a first digital signal corresponding to the first phase shift. A second phase modulation component introduces a second phase shift into the first local oscillator signal based upon the second control signal and generates a second digital signal corresponding to the second phase shift. A combination element is configured to combine the first and second digital output signals to generate an RF pulse width modulated (RF-PWM) signal.

    Abstract: A nonlinear distorter is configured to mitigate nonlinearity from a nonlinear component of a nonlinear system. The nonlinear distorter operates to model the nonlinearity as a function of a piecewise polynomial approximation applied to segments of a nonlinear function of the nonlinearity. The nonlinear distorter generates a model output that decreases the nonlinearity of the nonlinear component.

    Abstract: In accordance with an embodiment, a method for operating a millimeter-wave power amplifier including an input transistor having an output node coupled to a load path of a cascode transistor includes: receiving a millimeter-wave transmit signal at a control node of the input transistor; amplifying the millimeter-wave transmit signal to form an output signal; providing the output signal to a load coupled to an output node of the cascode transistor; and adjusting a first DC bias current of the input transistor to form a substantially constant second DC bias current of the cascode transistor.
