Hello all,


I would like to know HiK cahrge pump Mode of HMC835LP6GE.


According to the datasheet of HMC835, This mode is only recommended with external VCOs and active loop filter. Are there any problems if we use the mode by internal VCO and passive loop filter?


We can not find any problem about  HiK cahrge pump Mode using  internal VCO and passive loop filter by Hittite evaluation board of HMC835. Would you please tell us what kind of problem will be occure in this case. And/or, what kind of prrfomance should we evaluate carefully for using this way?


Thanks & Regards,
