Hello ,everybody, In my antenna switch,in order to get more than 4 ampers carrying capacity,i have to use wider trace width >80 mil. In order to improve the isolation ,i am going to utilize coplanar waveguide construction. but according to the calculation of AppCAD,with 80 mil trace width,the gap may up to 350 mil,is it right for a 30mil substrate? Any help will be appreciated!
PS:Substrate Thickness,30mil;copper thickness,2.8mil,dielectric constant,3.5.
at the same time ,i use Txline to calculate,but have different result,i don't know why!
