hi
for designing Lna at 2 GHz i think GML 1000 will be good enough
it is less cost as compared to FR4
u can try this gml 1000 i think it is frm gil technologies
i used the same & it is good

Please give us some price info on the GIL material, compared to FR4 and rogers 3000 and 4000 series.
Thanks

i work with it up to 3.5 ghz, and got good results

Are u sure?
I have made a design fro WLAN using FR4 as it has low price. My conclusion also stated that i do not recommend FR4 print.

Regarding dielectric constant, i mean FR4are availble in differnet layers, where the producers define the exact dielectric constant. The one i used had a constan of 4.7

hi olxx
The dielectrical constant of FR4 is 4.4,topic at 10GHz
It is usually used at the frequency low 5GHz.
Regards
