ADF4360-1 output power

I see the datasheet means that the output power is between -6dBm to -13dBm,this means the max output is -6dBm and I need this value,and I also use the recommended circuit at the output .Why do I get the output of 0.74dBm.Otherwise I see the datasheet gives a figure of typical result of near to 0dBm,so how to comprehend these?
