Abstract
The application discloses a radio transmission device (1) for receiving/transmitting of radio packets, comprising a reception means (34) arranged to receive radio signals, a phase locked loop (14) designed to be locked to a multiple of a reference oscillator (8) frequency, a mixing means (4) having its inputs connected to said reception means (34) and said phase locked loop (14), an intermediate frequency filtering means (6) having its input connected to the output of said mixing means (4), a demodulation means (12) connected to the output of the intermediate frequency filtering means (6) and a base band processing means (20) connected to the output of the demodulation means (12). A branch off line is connected between the reference oscillator (8) and the phase locked loop (14), a frequency dividing means (10), releaseably connected to said branch off line to divide the reference frequency of said reference oscillator (8), the output of said frequency dividing means (10) being connected with the input of said intermediate frequency filtering means (6) and said base band processing means (20) being connected to said reference oscillator (8). <IMAGE>
