  • Radio receiver and a radio transmitter
    Patent number: 6373883
    Abstract: A radio receiver is adapted to receive radio signals in at least two frequency bands, in which the radio signals are modulated by information signals. The radio receiver includes a device for down-converting a received radio signal to an intermediate frequency signal by using a local oscillator, and a demodulating device for recovering the information signals from the intermediate frequency signal. The frequency of the local oscillator is selected so that the frequencies of at least one of the frequency bands are above the frequency of the local oscillator, and the frequencies of at least one of the frequency bands are below the frequency of the local oscillator.
