HMC836LP6CE  REG settings and CONFIGURATION files

I wanna produce a signal with HMC836LP6CE kit  which is pll with RF VCO. And I have operated as the USER-GUIDE tells, but i can't get the right signal .When I set the output frequency in  3.5GHz on the PLL Eval Software,the RFoutput is only in about 1.6GHz with Vpp 20mV which  is apparantly not according with the datasheet of this PLL. So can  some experienced engineer offer me the right REG and  CONFIGURATION files.Thanks a lot.

    The HMC836 output component values should match the following and the eval board number is 125998-3.  Use the "hmc836_Frac" eval board register configuration file.

    R8=22

    L4=1.5nH

    L1=10nH

    C8=8.2pF

    C29=1.2pF

    C31=not installed
