Problems of flipped-chip MMIC at millimeter-wave frequency are investigated. Practical design criteria are introduced to obtain resonance and cutoff frequency for parasitic mode with flipped-chip MMIC structure. We investigate the advantages and disadvantages of three types of transmission line for flipped-chip MMIC in both electromagnetic simulation and scale-model. To avoid the resonance in coplanar waveguide flipped-chip MMIC new bridge structure is proposed.
