The radio-frequency signal reception and/or transmission device includes an antenna (8) for picking up or transmitting radio-frequency signals, a bandpass filter (9), at least one low noise amplifier (11) for amplifying the filtered signals, an oscillator stage (1) for generating first high frequency signals (SVCO), at least one frequency divider (14) for dividing by M the frequency of the first signals in order to generate second high frequency signals (SD), where M is an integer number greater than 1, at least a first mixer unit (12) for mixing the filtered and amplified radio-frequency signals (SR) with the first high frequency signals (SVCO), and at least a second mixer unit (13) for mixing the intermediate signals supplied by the first mixer unit with the second high frequency signals in order to produce baseband signals (IR, QR). The stage oscillator (1) is configured to generate first high frequency signals (SVCO), whose frequency is outside the frequency band of the bandpass filter and higher than the frequency of the received radio-frequency signals by a factor M/N comprised between 1 and 2, where N is an integer number greater than 1.
摘要:
The radio-frequency signal frequency conversion device generates intermediate complex signals (IF) for a correlation stage of a low power RF receiver. In order to do this, the device includes a first selective pass-band filter for filtering radio-frequency signals picked up by an antenna. A frequency synthesizer generates first and second high frequency signals, wherein the frequency of the first signals is higher than the frequency of the second signals. This synthesizer receives reference signals from an oscillator unit. A first mixer unit mixes the radio-frequency signals with the first signals in order to generate frequency-converted signals. A second pass-band filter filters the signals from the first mixer unit, and provides signals to a second mixer unit to mix them with the second high frequency signals. Finally, shaping means for the signals provided by the second mixer unit generate the intermediate signals. The second filter is a not very selective active filter, which is integrated, in an RF/IF integrated circuit with the first and second mixer units, the signal shaping means, and certain parts of the synthesizer and the oscillator unit.

The local oscillator stage is configured automatically by a control signal (Cm) from the processing unit to adapt the frequency of the oscillating signals (Sm) in accordance with the incoming radio-synchronous signal frequency, so that the intermediate signal (IF) frequency is within the frequency band of the bandpass filter.
