Hi,
I am a newcomer in LNA design, I am trying to design a LNA for 10.8-12 GHz using NE3511S02 transistor. The transistor is unconditionally stable for design frequencies but is potentially unstable below 10 Ghz. The problem I facing as I add load and source matching networks, my circuit becomes unstable. I am wondering if un-stabilities at lower frequencies r making my circuit unstable or what else could be a problem???
I would be very much thankful if someone who have used NE3511S02 for LNA design may post his/her design as example.
