摘要： The demodulator by direct frequency conversion comprises a vector addition device having: a first circuit (1) that furnishes, starting from a first AC signal (LO), a respective AC signal to n outputs that are not all of the same amplitude and of the same frequency, but are out of phase with regard to one another in such a manner that each one is not either in phase nor in opposite phase with any other; a second circuit (2) that splits a second AC signal (RFin) toward n outputs; a number n of summers (3a, 3b, 3c) each receiving, at the input, a respective output of the first circuit (1) and a respective output of the second circuit (2), and; a respective power sensor (4a, 4b, 4c) for each summer, whereby the number n is greater than or equal to 3. The demodulator also comprises digital processing means (5, 6) that furnish the result of the demodulation.

摘要： In one embodiment, a circuit provides two quadrature components, I and Q, from a received modulated signal, from three mutually phase-shifted components of the received signal. The circuit can demodulate three mutually phase-shifted components of a baseband signal, in order to provide two quadrature demodulation components. The circuit includes three circuit inputs, each designed to received said three components, respectively. The circuit further includes a first and second adder circuit. The circuit also includes a bank of weighting circuits linked, at input, to the three circuit inputs and linked, at output, to the inputs of the first and second adder circuits so as to transmit to each adder input, with a determined weighting, a particular one of said three components, the weightings being chosen so that the first and second adder circuits provide said two quadrature demodulation components.
