Hi everybody
I am new in Rf design.
I am trying to design a 5.8 GHz LNA
and i don't know how much Resistors and capacitors are acceptable for that.
for example my i have a 4K ohm bias resistor,is that OK?or not?
or is 1pF capacitor for coupling stages is good or not?

thanks for your helps.!
 

Hi, ahya

I do not know which resistor you refer to, there can be many bias resistors depending on what bias circuit you are going to design.
How large the capacitor is depends on how large your inductor is. Also you need to consider parasitics of your inductor and transistors.
It's better if you can post your schematic out.
