I want to use the HMC980 to bias the HMC950. From the datasheet of HMC980:
VDD = 7.7V
IDRAIN = 820mA
RSENSE = 183Ohm
The question is：
1. R3, R4 are open, is that means they are “no connect” ?
2. How to change VNEG = -2.0V ?
3. How much current will the VDD pin need?
4. What will happen if VDD > 7.7V ?
5. How to find a suitable solution to ensure VDD = 7.7V? Can I use Switching Regulators to connect VDD?
