Thank you very much dyoung1,
Please attached example configuration files for HMC765 and HMC820 (f0/2 mode board). File which you attached is only HMC820 (f0 mode).

I've attached the HMC820 and HMC765 gerber files.
I have used HMC833 HMC830 HMC840 HMC829 HMC820。
I need to improve my PLLVCO products phase noise。
想要得到4.8GHz信号，但按照手册上所说，VCO Reg02设置为8395 ，VCO Reg03设置为D11D，始终输出2.4G左右信号，4.8G附近有输出但是功率特别低。请问应该怎么配置寄存器才能只输出2倍频？
Both HMC830 and HMC832 will meet these requirements but the application must utilize a tunable reference and manual tuning to meet the -60dBc spurious and hop time requirements. I've attached an appnote on manual tuning. With a fixed 50MHz reference Figure…
Hello,
I'm working with the PLL VCO HMC830.
I want to use a look-up table (LUT) for manual calibration, as decribe in "Frequency Hopping with Hittite PLLVCOs Application Note" (attached) (https : // www . hittite.com/content/documents/application_notes…
HMC820锁相环工作大于3个月时间后有些芯片失锁有30%（大概有100块），通过重新更换锁相环芯片的方式，主板正常工作，现在想读取锁相环里面的程序，请问有什么办法吗？现在找不到失锁的原因。
Use the ADP150 regulator; good performance, low cost.

Thanks a lot. So, at a high level, this does work: I first load HMC834 into the evaluation software and get it to lock by loading its register file. Then, I close the evaluation software and open it again, but this time using HMC820 settings (the lock…
