Abstract :
At high frequencies, grounded coplanar waveguide MMIC circuits can be prone to destructive intercircuit coupling effects due to substrate resonances. Analytic formulas for a simple circuit model of this coupling are presented in this paper. The model can be used with commercially available CAD in order to estimate the importance of such coupling for a particular circuit and substrate configuration. Results predicted by this model are compared to numerically rigorous spectral domain results and to experiment
