Abstract:
1. A transceiver, comprising: an RF receiver with a digital signal processing device in a digital part with an input part; at least one mixer; and an intermediate frequency and baseband processing device having a local channel oscillator to which a first phase locked loop with a phase discriminator and an adjustable first frequency converter are assigned, and having a reference oscillator for the first phase locked loop and a control clock of the digital signal processing device, wherein to acquire the control clock, a digital clock synthesizer is provided to which an upward signal of the reference oscillator is supplied, and a control signal is supplied by the digital part in the form of a digital tuning word, the frequency of the reference oscillator being selected such that its order of magnitude is at least equal to the bandwidth of one or more of the reception bands of said RF receiver used and harmonics do not occur in a reception channel.
