Accurate Characterisation and Modelling of Transmission Lines for GaAs MMICs

The benefits of the spectral domain hybrid mode approach in the design of multi dielectric media transmission lines is described. Using GaAs ring resonator techniques covering 2 to 24 GHz, accuracies in effective dielectric constant and loss of 1% and 15% respectively are presented. By combining theoretical and experimental techniques a generalised MMIC microstrip design data base is outlined.
