Geodetic VLBI experiments are usually conducted at S and X bands. Significant advantages could be gained making observations at a higher frequency band like, for example, the 22 GHz (K band), where many radioastronomical observatories have suitable receivers. In order to check the feasibility and reliability of this new configuration, we organized a VLBI experiment, on February 1991, between the Kashima 34 m antenna in Japan and the Medicina 32 m radiotelescope in Italy. A new phase calibration system, suitable for operation at K band and developed at CRL, was used at that time with both antennas. This phase calibrator utilizes an up-conversion method which can be modified to operate at any other receiving frequency band.
