THANK YOU VERY MUCH SIR, I WANT TO DO A CO DESIGN OF THE LNA AND ANTENNA BUT WITH THE LT SPICE THIS WILL NOT BE POSSIBLE ALSO .. KINDLY ADVICE SIROch, oum. The same way as every transistor circuit, but taking in account the impedance and matching. And if for general circuit there are no way better modelling soft as LT-Spice, then for specifically RF upper end there are no way better soft as RF-Sim-99.
Thank you very much sirRE:""i have not designed any transistor circuit before"" thatswhy I begun my reply with shout of extreme surprize. So I shall speak it loud - please not take it insulting, please, it is just the very very good advice: never buy Your first vehicle in life Ferrari, never build Your first handmade aircraft the Boeing, and never begin Your electronics designer experience with highest pilotage like LNA. Begin with moderate simple things, and if You shall learn to make thinking via the soldering hammer tip, You soon will be able to make even LNA. But not as the first construction into life. Just, without a good VNA and modelling skills and sense of PCB geometry in terms of EM volatiles it will give only disappointment. It all will come within a proper time. By the way, Warmly recommend to read two books, each two volume by 1000 pages, first is Titze&Schenk and other is Horowitz&Hill. After many things will become clear by itself. Those both books have a zillions cracked copies at all around the world, even nearer than dark-web.
I remember working with such a part almost 50 years ago. They were extremely static sensitive and came with a shorting wire on the leads to prevent accidental potential differences being applied in handling. The circuit I was working with never worked and I haven't had occasion to use one since. The reason you might be having trouble finding information could be because there is non available. Do you know for a fact that anybody still makes such a part? Have you checked with any large distributors like Digi-key or Mouser?I clearly understand and appreciate all the suggestions and mentioned comments. I am under pressure to do a simulation of LNA using double gate MOSFET I tried searching for double gate MOSFET transistor in the ADS design kits but could not find any can somebody please tell me an alternative to this in the ADS software... Let me settle this first I will follow your suggestions and see how to download the suggested books Thank you Seniors
