hello everyone:

I need to design a power amplifier in 14-16GHz. I have decided to use EID1416-12. This FET is a internally matched power FET. Several parameters of it in continuous state show as follows: Vds=10v Vgs=-3v Id(1dB)=4A(max=5A) G(1dB)=5dB. We can find it has very high channel current. So I hope someone can give me some advices about its direct current bias design or others which I need to notice.Thanks!!!

regards

hi

i want to design biasing network for GaAs FET so anybody tell how to design biasing networks and how to check the designed biasing network is correct or not..


i have designed biasing network but i dont know how to check my biasing network is correct or not
 

Post the schematics and layout here so we can take a look.
 

hi to all

im attaching schematic diagram .so plz give me a reply...
