摘要： Circuits and methods for use in amplifying amplitude and phase modulated signals. A circuit uses a combiner with dual parallel signal amplifiers feeding it. The signal amplifiers have a low output impedance while the combiner does not provide any isolation between its inputs from the signal amplifiers. As in other Chireix architectures, the signals from the signal amplifiers are phase modulated prior to being fed to the combiner. The combiner then combines these two signals and, depending on how these two signals are combined, the resulting output of the combiner is amplitude modulated. The signal amplifiers may be Class D or Class F amplifiers to provide high efficiency amplification of the signals.

摘要： A method and apparatus for generating an amplitude-modulated signal based on a modulation signal including first and second digital oscillators which are controlled based on first and second phase shifts derived from the modulation signal, and output first and second phase-modulated signals having a same amplitude and first and second phases, respectively; first and second amplification channels which amplify the first and second phase-modulated signals, respectively, and output first and second amplified phase-modulated signals; an adder which adds the first and second amplified phase-modulated signals and outputs a resultant amplitude-modulated signal; and a filter which filters the resultant amplitude-modulated signal and outputs the amplitude-modulated signal. The method and apparatus for amplitude modulation is suited for applications in "solid state" power transmitters.

摘要： In a modualtion system responsive to a first sampled signal (31) of a first sampling rate for supplying a modulated analog signal to an amplifier having nonlinearities to make the amplifier produce an amplified output signal, a selector (72) selects the first sampled signal and a second sampled signal of a second sampling rate as a selected signal when supplied with first and second control signals, respectively. The second sampling rate is equal to 1/N (N: 2, 3, . . . ) of the first sampling rate. A processing arrangement (36) processes the selected signal with reference to a difference between the selected signal and an additional digital signal (35) to compensate for the nonlinearities to produce a processed signal. The processed signal is modulated into the modulated analog signal. The amplified output signal is demodulated and converted into the additional digital signal by a converter (40). A comparator (71) compares an absolute value of the difference with a threshold value and produces the first control signal when the absolute value is less than the threshold value. Otherwise, the second control signal is produced. A controller ( 78) may control a phase of a sampling signal supplied to the converter so that a quotient of the difference by a differential of the selected signal becomes equal to zero.
