Hi,
I am using HMC920 to bias HMC863ALC4.
Queries:
1)In HM920 what is the relation between VDD and VDIG?
2) Do I need to apply voltage to VDIG as below?
3) Is there a reference circuit for the connection of HMC920 and HMC863ALC4?

Hi Ivan,
some question need to check again.
1.
from the HMC920 datasheet, page17,
for Vldocc=5.65V, why R8 (i.e. R10) =16.1K ohm, NOT 18.2K ohm
2.
from the HMC920 datasheet, page18,
for Idrain=350mA, why Rsense =390 ohm, NOT 470 ohm
thanks,
Yufan
