The loop filter's BW is so strange on my HMC838 board, The BW gets so large at lower frequency(1.62GHz) and get smaller at high frequency(1.67Ghz). and also the phase noise get worse at low frequency, and actually it is not good enough at high frequency. the settings of the design are: Fref:19.2MHz, PFD:19.2MHz, Fout:16.GHz~1.7GHz, BW:50KHz. there are two plots were attached. Any suggestions? Thanks!

I think you asked the same question in Chinese. The loop bandwidth will not vary a lot over different freq since the VCO inside the part is really narrow band. We suggest you double check your loop filter or use the loop in the datasheet with 50MHz Ref.
