    摘要： A radiofrequency signal power amplification circuit may include a signal input for receiving the radiofrequency signal, an amplification stage coupled to the signal input and having at least one power transistor, a biasing stage for delivering a bias voltage to the amplification stage, and a processing stage. The processing stage may include a processing input coupled to the signal input, a processing output for delivering a bias current modulated at least in amplitude to the biasing stage, and an amplitude modulator coupled between the processing input and the processing output and configured to determine an envelope signal representative of the envelope of the radiofrequency signal, for modulating the amplitude of the envelope signal based on a variable voltage setpoint and for generating the amplitude-modulated bias current based on the modulated envelope signal.

    摘要： The frequency synthesizer includes a phase-locked loop (PLL). The PLL includes an oscillator controlled to deliver an output signal at a predefined output frequency, a variable frequency divider to convert the output signal into a divided-frequency signal, a phase comparator to produce a signal measuring a phase difference between the divided-frequency signal and a reference signal at a reference frequency, and a loop filter to control the oscillator on the basis of the measurement signal. To increase the speed of convergence of the synthesizer if the set point is changed, the loop filter of the PLL is a fractional, i.e. non-integer, order low-pass filter.
