Besides the mismatch of the HMC836 bias network and values with the eval board, can it be the wrong(or inproper ) PLL Eval Software's settings that makes the output power weak?
Correction...
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 install…
想利用HMC836LP6CE产生一个3.5GHz的正弦信号，但是根据ADI上面的提供的USER-GUIDE操作时发现完全得不到正确信号，所产生的RF输出正弦波，不仅频率只有大概1.6GHz左右，而且Vpp大概只有15mV，而根据说明书上这个信号的典型值是6dbm，即便最低也有-1dbm，换算成Vpp的话大概是Vpp也有563mV。因此想请教一下有没有用过这款PLL的高手，指导一下。谢谢了！！！
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…
Use the ADP150 regulator; good performance, low cost.
