Abstract :
This paper proposes a new flip chip structure which uses resonating dual bumps to achieve best transition. By simply changing the distance between the two bumps, we can control the band of minimum reflection in the desired frequency band. The bandwidth over which the return loss is smaller than -20 dB is 20-30%. The corresponding insertion loss in this band is less than -1.5 dB. All, results presented are simulated with the FDTD method combined with PML.
