Tx LO leakage improvement

The LO leakage is at -50dBc on the transmit side, while on my design the LO frequency is set to 70 MHz, and the output frequency is 71 MHz. According to the datasheet, this could be expected; however I need at least a 10 dB better figure and believe that there exists calibration means in order to improve the LO leakage level. Are you aware of this and of can guide me on how to proceed please ?
