thanks Bluejets as always.
2 quick questions, are the resistor values dependent on anything?
can I use just the left side circuit so when M1 is on M2 is off and vice versa?
Am attempting a 12volt application here so if that helps with values.
Resistors are for proper biasing.
As shown the 10k pulldown is to ensure the mosfet goes off and stays off.
The 100R is for some series protection.
The 1K pullup ensures M2 operates correctly.
12v operation would suit most mosfets but that depends on which ones you use and what signal level you intend I'd imagine.
Looking at the circuit where it is operated by a "digital signal", one would assume that would be in the 5v area so use logic level mosfets.
It's not like they cost any more or are difficult to find.
Did you read the link??
Getting confused as to what you want here....do you have one load or two?

So, 120GHz. That will be a challenge.
