摘要： A transmission circuit that performs modulation based on a phase difference signal and an amplitude signal includes an asymmetrical phase rotation device. The asymmetrical phase rotation device performs an operation of subtracting 2π from a value of the phase difference signal when the value of the phase difference signal is greater than a predetermined positive threshold value, or an operation of adding 2π to the value of the phase difference signal when the value of the phase difference signal is less than a predetermined negative threshold value. Accordingly, the transmission circuit has distortion reduction characteristics improved uniformly over a range of frequencies higher or lower than a carrier wave band.

摘要： A low cost high-efficiency all-digital transmitter using all-digital power amplifiers (“DPA”) and various mapping techniques to generate an output signal, which substantially reproduces a baseband signal at a carrier frequency. A baseband signal generator generates a baseband signal which is quantized by a signal processor using a quantization map. A DPA control mapper outputs control signals to phase selectors using the quantized signal and a quantization table. Each phase selector receives one of the control signals and outputs a waveform at a carrier frequency with a phase corresponding to the control signals, or an inactive signal. Each DPA in a DPA array has an assigned weight, receives one of the waveforms from the phase selectors, and outputs a power signal according to the weight of the DPA and the phase of the received waveform. The combined power signal substantially reproduces the baseband signal at the carrier frequency.

摘要： A transmission circuit precisely compensates for an offset characteristic of an amplitude modulation section and operates with low distortion and high efficiency over a wide output power range. A signal generation section outputs an amplitude signal and an angle-modulated signal. An amplitude amplifying section supplies, to the amplitude modulation section, a voltage corresponding to a magnitude of an inputted amplitude signal. The amplitude modulation section amplitude-modulates the angle-modulated signal by the voltage supplied from the amplitude amplifying section, thereby outputting a resultant signal as a modulation signal. A temperature measuring section measures a temperature of the amplitude modulation section. An offset compensation section calculates an offset compensation value in accordance with a change, in temperature of the amplitude modulation section, from the temperature of the amplitude modulation section in an initial state, and adds the calculated offset compensation value to the amplitude signal.

摘要： The disclosure relates to a method and apparatus for providing efficient signal transmission. Conventional linear amplifiers are most efficient when operated in compressed mode. In the compressed mode, the digital power amplifier switches between the on and off modes. A digital power amplifier operates in compressed mode only if the incoming signal is an on-off constant envelop signal. In one embodiment, the disclosure provides a method and apparatus for converting a digital baseband signal to on-off constant envelop signals for processing through binary-weighted or thermometer-weighted amplifier which are operated in compressed mode.

摘要： A phase modulation section (101) generates a first modulated signal including phase information. An amplitude signal control section (103) generates a second modulated signal including amplitude information. A waveform shaping section (104), when an amplitude of the second modulated signal is larger than a regulated value generates a waveform-shaped modulated signal. An amplitude modulated voltage supply section (105) amplifies the waveform-shaped modulated signal based on the supply voltage from a voltage control section (106) and supplies the amplified signal to a power amplification section (102). The power amplification section (102) amplifies the first modulated signal based on the amplitude modulated voltage, and outputs the resultant signal. The waveform shaping section (104) adjusts the regulated value in accordance with a factor for changing a distorted power generated by the power amplification section (102), such that an ACP generated by the power amplification section (102) becomes a first predetermined value or smaller.

摘要： Data from the orthogonal data generator is quantized by the vector data converter to become, for example, a binary value of 0 and a real number in magnitude. The output of the vector converter is modulated by the modulator, and is inputted to the amplifier. In the amplifier, the envelope of the signal to be inputted is quantized. That is, the signal of a constant envelope becomes a signal which is turned ON and OFF, so that a highly efficient nonlinear amplifier can be used. The filter removes the quantization noise generated in the vector data converter and then the signal of a low distortion and a low noise is outputted from the output terminal. The isolation unit is connected between the amplifier and the filter, avoiding effects on the output impedance of the amplifier from the filter, so that a signal of a low distortion can be outputted.
