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?
Dear sir:
have any update?
Hi ADI,
I have the same question. Does ADI has any update?
I'm confused by HMC920 datasheet. I can't find R1 & R3.
The datasheet is not easy to read and understand.
Hi Yufan, Mina,
You do not need to two anything for Vdig.
In order to set Vdrain=5.5V and Idd=350mA:
Vd= 6.2V, Vldocc=5.65V, Rsense = 390 Ohm and R10 = 16.1k Ohms.
Regards
Ivan
