A CAD-SUITABLE APPROACH FOR THE ANALYSIS OF NONUNIFORM MMIC AND MHMICTRANSMISSION-LINES

A neu method of moment-based formulation for the solution of the teleg raphist's equations in nonuniform transmission lines is presented, Ent ire domain basis functions that build in a frequency variation are use d to cover wider frequency and physical dimension ranges. The results obtained using the proposed formulation are validated by comparison to those obtained by a CAD package and to measured data. Different nonun iform lines in microstrip and coplanar technologies on monolithic micr owave/millimeter wave integrated circuit (MMIC) and miniaturized hybri d microwave integrated circuit (MHMIC) substrates are investigated wit h an application to the design a matched taper transition in a MMIC co planar line.
