Hello Andy , sorry for misunderstanding. I will try to make my self more clearly
Yhe resistor is an rf transistor ,according figure 12 in the datasheet it needs to be Vds=45V and Ids=15A so the equivalent rds=3Ohm.
I need to bias two such transistors so 3||3=1.5 equivalent load.
As described in the photo below,The floating voltage opens M1 mosfet ,the current from M1 goes into two CGHV1A250F GAN M4 and M5 transistors(which i dont have their spice model) so i used 3||3=1.5.
M4 and M5 will be used to amplify RF signal.
If i put GND to the VSS of UCC5304 then i will have GND on the drain of my M4 and M5 then i would not be able to open them.
This is the LTSPICE riddle , how can i put VSS=GND? it will totally disable my options to open M4 and M5 later.
Maybe i am missign something in the logic of connecting the UCC5304 to the M1 ?
Thanks.
